New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	NOTE 2: RECENT ACCOUNTING PRONOUNCEMENTS Impact of Recently Issued Accounting Standards—Adopted In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-07, “ Investments – Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting .” The amendment eliminates the retroactive adjustments to an investment upon it qualifying for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence by the investor. ASU 2016-07 requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment qualifies for equity method accounting. The update was effective for interim and annual reporting periods beginning after December 15, 2016. We adopted this guidance for our fiscal year beginning January 1, 2017. The adoption of this guidance did not have an impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, “ Clarifying the Definition of a Business In January 2017, the FASB issued ASU 2017-04, “ Simplifying the Test for Goodwill Impairment Impact of Recently Issued Accounting Standards—Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers, Revenue from Contracts with Customers Revenue Recognition. Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing” In January 2016, the FASB issued ASU 2016-01, " Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. he amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption. Early adoption is permitted. We will adopt this guidance for our fiscal year beginning January 1, 2018. We are still assessing the impact of adoption on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “ Leases ” codified in ASC 842, “ Leases. ” The guidance requires that lessees will be required to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The amendment also will require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative information. The update is effective for interim and annual reporting periods beginning after December 15, 2018. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements, and have the option to use certain relief. Full retrospective application is prohibited. Early adoption is permitted. We will adopt this guidance for our fiscal year beginning January 1, 2019. We are still assessing the impact of adoption on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, “ Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments. ” The amendment requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected, thus eliminating the probable initial recognition threshold and instead reflecting the current estimate of all expected credit losses. The amendment also requires that credit losses relating to available-for-sale debt securities be recorded through an allowance for credit losses rather than a write-down, thus enabling the ability to record reversals of credit losses in current period net income. The update is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted . In August 2016, the FASB issued ASU 2016-15, “ Statement of Cash Flows – Classification of Certain Cash Receipts and Certain Cash Payments. ” The amendments address the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The update is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements In October 2016, the FASB issued ASU 2016-16, “Income Taxes – Intra-Entity Transfers of Assets Other Than Inventory . ” In November 2016, the FASB issued ASU 2016-18 “Statement of Cash Flows – Restricted Cash.” The amendments should be applied using a retrospective transition method to each period presented. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements .

At March 31, 2017 , Ryerson had $334.3 million of outstanding borrowings, $16 million of letters of credit issued and $250 million available under The Ryerson Credit Facility has an allocation of $660 million to the Company’s subsidiaries in the United States and an allocation of $90 million to Ryerson Holding’s Canadian subsidiary that is a borrower. Amounts outstanding under the Ryerson Ryerson We attempt to minimize interest risk exposure through the utilization of interest rate swaps, which are derivative financial instruments. On March 3, 2017 we entered into an interest rate swap to fix interest on $150 million of our floating rate debt under the Ryerson Credit Facility at a rate of 1.658% through March 2020. The swap has reset dates and critical terms that match our existing debt and the anticipated critical terms of future debt. The weighted average interest rate on the outstanding borrowings under the Ryerson Credit Facility including the interest rate swap was 2.7 percent and 2.2 percent at March 31, 2017 and December 31, 2016, respectively. Borrowings under the Ryerson The Ryerson Ryerson Ryerson The Ryerson Ryerson Ryerson The lenders under the Ryerson Ryerson Proceeds from borrowings under the Ryerson Ryerson Ryerson 2022 Notes On May 24, 2016, JT Ryerson issued $650 million in aggregate principal amount of the 2022 Notes (the “2022 Notes”). The 2022 Notes bear interest at a rate of 11.00% per annum. The 2022 Notes are fully and unconditionally guaranteed on a senior secured basis by all of our existing and future domestic subsidiaries that are co-borrowers or that have guarantee obligations under the Ryerson Credit Facility. The 2022 Notes and the related guarantees are secured by a first-priority security interest in substantially all of JT Ryerson’s and each guarantor’s present and future assets located in the United States (other than receivables, inventory, money, deposit accounts and related general intangibles, certain other assets and proceeds thereof), subject to certain exceptions and customary permitted liens. The 2022 Notes and the related guarantees are also secured on a second-priority basis by a lien on the assets that secure JT Ryerson’s and the Company’s obligations under the Ryerson Credit Facility. The 2022 Notes will be redeemable, in whole or in part, at any time on or after May 15, 2019 at certain redemption prices. The redemption price for the 2022 Notes if redeemed during the twelve months beginning (i) May 15, 2019 is 105.50%, (ii) May 15, 2020 is 102.75%, and (iii) May 15, 2021 and thereafter is 100.00%. JT Ryerson may redeem some or all of the 2022 Notes before May 15, 2019 at a redemption price of 100.00% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, plus a “make-whole” premium. In addition, JT Ryerson may redeem up to 35% of the 2022 Notes before May 15, 2019 with respect to the 2022 Notes with the net cash proceeds from certain equity offerings at a price equal to 111.00%, with respect to the 2022 Notes, of the principal amount thereof, plus any accrued and unpaid interest, if any. JT Ryerson may be required to make an offer to purchase the 2022 Notes upon the sale of assets or upon a change of control. The 2022 Notes contain customary covenants that, among other things, limit, subject to certain exceptions, our ability, and the ability of our restricted subsidiaries, to incur additional indebtedness, pay dividends on our capital stock or repurchase our capital stock, make investments, sell assets, engage in acquisitions, mergers or consolidations or create liens or use assets as security in other transactions. Subject to certain exceptions, JT Ryerson may only pay dividends to Ryerson Holding to the extent of 50% of future net income, once prior losses are offset. During the first three months of 2016, a principal amount of $25.1 million of the 11.25% Senior Secured Notes due 2018 (the “2018 Notes”) were repurchased for $16.9 million and retired, resulting in the recognition of a $8.2 million gain within other income and (expense), net on the Condensed Consolidated Statement of Comprehensive Income.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 8: COMMITMENTS AND CONTINGENCIES In October 2011, the United States Environmental Protection Agency (the “EPA”) named us as one of more than 100 businesses that may be a potentially responsible party for the Portland Harbor Superfund Site (the “PHS Site”). On January 6, 2017, the EPA issued its Record of Decision (“ROD”) regarding the site. The ROD includes a combination of dredging, capping and enhanced natural recovery that would take approximately thirteen years to construct plus additional time for monitored natural recovery, at an estimated present value cost of $1.05 billion. The EPA has not yet allocated responsibility for the contamination among the potentially responsible parties, including JT Ryerson. We do not currently have sufficient information available to us to determine whether the ROD will be executed as currently stated, whether and to what extent JT Ryerson may be held responsible for any of the identified contamination, and how much (if any) of the final plan’s costs might ultimately be allocated to JT Ryerson. Therefore, management cannot predict the ultimate outcome of this matter or estimate a range of potential loss at this time. There are various other claims and pending actions against the Company. The amount of liability, if any, for those claims and actions at March 31, 2017 is not determinable but, in the opinion of management, such liability, if any, will not have a material adverse effect on the Company’s financial position, results of operations or cash flows. We maintain liability insurance coverage to assist in protecting our assets from losses arising from or related to activities associated with business operations.

Derivatives and Fair Value Measurements	NOTE 9: DERIVATIVES AND FAIR VALUE MEASUREMENTS Derivatives The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are interest rate risk, foreign currency risk, and commodity price risk. Interest rate swaps are entered into to manage interest rate risk associated with the Company’s floating-rate borrowings. We use foreign currency exchange contracts to hedge our Canadian subsidiaries’ variability in cash flows from the forecasted payment of currencies other than the functional currency. From time to time, we may enter into fixed price sales contracts with our customers for certain of our inventory components. We may enter into metal commodity futures and options contracts periodically to reduce volatility in the price of metals. We may also enter into natural gas and diesel fuel price swaps to manage the price risk of forecasted purchases of natural gas and diesel fuel. The Company currently does not account for its commodity contracts and foreign exchange derivative contracts as hedges but rather marks them to market with a corresponding offset to current earnings. The Company accounts for its interest rate swap as a cash flow hedge of floating-rate borrowings with changes in fair value being recorded in accumulated other comprehensive income. We have a receive variable, pay fixed interest rate swap to manage the exposure to variable interest rates of our credit facility. On March 3, 2017, we entered into a forward agreement for $150 million of “pay fixed” interest at 1.658%, “receive variable” interest rate swap to manage the risk of increasing variable interest rates. The interest rate reset dates and critical terms match the terms of our existing debt and anticipated critical terms of future debt under the Ryerson Credit Facility. The fair value of the interest rate swaps as of March 31, 2017 was zero. Total gains or losses recognized on the hedge for the three months ended March 31, 2017 was zero. The Company regularly reviews the creditworthiness of its derivative counterparties and does not expect to incur a significant loss from the failure of any counterparties to perform under any agreements. The following table summarizes the location and fair value amount of our derivative instruments reported in our Condensed Consolidated Balance Sheets as of March 31, 2017 and December 31, 2016: Asset Derivatives Liability Derivatives Derivatives not designated as hedging instruments under ASC 815 Balance Sheet Location March 31, 2017 December 31, 2016 Balance Sheet Location March 31, 2017 December 31, 2016 (In millions) Commodity contracts Prepaid expenses and other current assets 2.7 2.0 Other accrued liabilities 1.0 0.2 Total derivatives $ 2.7 $ 2.0 $ 1.0 $ 0.2 As of March 31, 2017 and December 31, 2016, the Company’s foreign currency exchange contracts had a U.S. dollar notional amount of $2.4 million and $2.3 million tons had The following table summarizes the location and amount of gains and losses reported in our Condensed Consolidated Statements of Comprehensive Income for the three months ended March 31, 2017 and 2016: Amount of Gain/(Loss) Recognized in Income on Derivatives Derivatives Location of Gain/(Loss) Recognized Three Months Ended March 31, instruments under ASC 815 in Income on Derivatives 2017 2016 (In millions) Metal commodity contracts Cost of materials sold $ 1.3 $ 2.2 Foreign exchange contracts Other income and (expense), net — (0.2 ) Total $ 1.3 $ 2.0 Fair Value Measurements To increase consistency and comparability in fair value measurements, ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows: 1. Level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the reporting date. 2.

The Company has various commodity derivatives to lock in nickel prices for varying time periods. The fair value of these derivatives is determined based on the spot price each individual contract was purchased at and compared with the one-month daily average actual spot price on the London Metals Exchange for nickel on the valuation date. The Company also has commodity derivatives to lock in hot roll coil, iron ore, and aluminum prices for varying time periods. The fair value of hot roll coil, iron ore, and aluminum derivatives is determined based on the spot price each individual contract was purchased at and compared with the one-month daily average actual spot price on the Chicago Mercantile Exchange, the Singapore Exchange, and the London Metals Exchange, respectively, for the commodity on the valuation date. The Company has various commodity derivatives to lock in diesel prices for varying time periods. The fair value of these derivatives is determined based on the spot price each individual contract was purchased at and compared with the one-month daily average actual spot price of the Platts Index for Gulf Coast Ultra Low Sulfur Diesel on the valuation date. In addition, the Company has numerous foreign exchange contracts to hedge our Canadian subsidiaries’ variability in cash flows from the forecasted payment of currencies other than the functional currency, the Canadian dollar. The Company defines the fair value of foreign exchange contracts as the amount of the difference between the contracted and current market value at the end of the period. The Company estimates the current market value of foreign exchange contracts by obtaining month-end market quotes of foreign exchange rates and forward rates for contracts with similar terms. The Company uses the exchange rates provided by Reuters. Each commodity and foreign exchange contract term varies in the number of months, but on average is between 3 to 12 months The carrying and estimated fair values of our financial instruments at March 31, 2017 and December 31, 2016 were as follows: At March 31, 2017 At December 31, 2016 Carrying Amount Fair Value Carrying Amount Fair Value (In millions) Cash and cash equivalents $ 72.1 $ 72.1 $ 80.7 $ 80.7 Restricted cash 1.2 1.2 1.0 1.0 Receivables less provision for allowances, claims and doubtful accounts 413.7 413.7 326.0 326.0 Accounts payable 337.0 337.0 230.4 230.4 Long-term debt, including current portion 992.5 1,074.5 963.5 1,034.2 The estimated fair value of the Company’s cash and cash equivalents, receivables less provision for allowances, claims and doubtful accounts and accounts payable approximate their carrying amounts due to the short-term nature of these financial instruments. The estimated fair value of the Company’s long-term debt and the current portions thereof is determined by using quoted market prices of Company debt securities (Level 2 inputs). Assets Held for Sale The Company had $1.6 million and $3.6 million of assets held for sale, classified within “prepaid expenses and other current assets,” as of March 31, 2017 and December 31, 2016. The fair values less costs to sell of long-lived assets held for sale are assessed each reporting period that they remain classified as held for sale. Any increase or decrease in the held for sale long-lived asset’s fair value less cost to sell is reported as an adjustment to its carrying amount, except that the adjusted carrying amount cannot exceed the carrying amount of the long-lived asset at the time it was initially classified as held for sale. The fair values of each property were determined based on appraisals obtained from a third-party, pending sales contracts, or recent listing agreements with third-party brokerage firms (Level 2 inputs). The following table presents those assets that were measured at fair value on our Condensed Consolidated Balance Sheet on a non-recurring basis and their level within the fair value hierarchy at March 31, 2017: At March 31, 2017 Level 1 Level 2 Level 3 (In millions) Assets Prepaid expenses and other current assets – assets held for sale $ — $ 1.6 $ — The following table presents those assets that were measured and recorded at fair value on our Condensed Consolidated Balance Sheet on a non-recurring basis and their level within the fair value hierarchy at December 31, 2016: At December 31, 2016 Level 1 Level 2 Level 3 (In millions) Assets Prepaid expenses and other current assets – assets held for sale $ — $ 3.6 $ — Available-For-Sale Investments The Company has classified investments made during 2010 and 2012 as available-for-sale at the time of their purchase. Investments classified as available-for-sale are recorded at fair value with the related unrealized gains and losses included in accumulated other comprehensive income. Management evaluates investments in an unrealized loss position on whether an other-than-temporary impairment has occurred on a periodic basis. Factors considered by management in assessing whether an other-than-temporary impairment has occurred include: the nature of the investment; whether the decline in fair value is attributable to specific adverse conditions affecting the investment; the financial condition of the investee; the severity and the duration of the impairment; and whether we intend to sell the investment or will be required to sell the investment before recovery of its amortized cost basis. When it is determined that an other-than-temporary impairment has occurred, the investment is written down to its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred. As of March 31, 2017, the investment was in a breakeven position. Management does not currently intend to sell the investment before recovery of its adjusted cost basis. Realized gains and losses are recorded within the Condensed Consolidated Statement of Comprehensive Income upon sale of the security and are based on specific identification. The Company’s available-for-sale securities as of March 31, 2017 can be summarized as follows: At March 31, 2017 Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (In millions) Common stock $ 0.4 $ — $ — $ 0.4 The Company’s available-for-sale securities as of December 31, 2016 can be summarized as follows: At December 31, 2016 Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (In millions) Common stock $ 0.4 $ — $ — $ 0.4 There is no maturity date for these investments and there have been no sales

Eligible accounts receivable, at any date of determination, is comprised of the aggregate value of all accounts directly created by a borrower (and in the case of Canadian accounts, a Canadian guarantor) in the ordinary course of business arising out of the sale of goods or the rendering of services, each of which has been invoiced, with such receivables adjusted to exclude various ineligible accounts, including, among other things, those to which a borrower (or guarantor, as applicable) does not have sole and absolute title and accounts arising out of a sale to an employee, officer, director, or affiliate of a borrower (or guarantor, as applicable). Eligible inventory, at any date of determination, is comprised of the net orderly liquidation value of all inventory owned by a borrower (and in the case of Canadian accounts, a Canadian guarantor). Qualified cash consists of cash in an eligible deposit account that is subject to customary restrictions and liens in favor of the lenders.
