Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of Presentation
	TimkenSteel Corporation (TimkenSteel) became an independent company as a result of the distribution on June 30, 2014 by The Timken Company (Timken) of 100 percent of the outstanding common shares of TimkenSteel to Timken shareholders. Each Timken shareholder of record as of the close of business on June 23, 2014 received one TimkenSteel common share for every two Timken common shares held as of the record date for the distribution. TimkenSteel common shares trade on the New York Stock Exchange under the ticker symbol “TMST.”
	Prior to the spinoff on June 30, 2014, TimkenSteel operated as a reportable segment of Timken. The accompanying Unaudited Consolidated Financial Statements for periods prior to the separation have been prepared from Timken’s historical accounting records and are presented on a stand-alone basis as if the operations had been conducted independently from Timken. The Unaudited Consolidated Financial Statements for periods prior to the separation include the historical results of operations, assets and liabilities of the legal entities that are considered to comprise TimkenSteel. The historical results of operations and cash flows of TimkenSteel presented in the Unaudited Consolidated Financial Statements for periods prior to the separation may not be indicative of what they would have been had TimkenSteel actually been a separate stand-alone entity during such periods, nor are they necessarily indicative of TimkenSteel’s future results of operations and cash flows.
	The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) and disclosures considered necessary for a fair presentation have been included. For further information, refer to TimkenSteel’s Audited Consolidated Financial Statements and Notes included in its Annual Report on Form 10-K for the year ended December 31, 2014.
	Certain items previously reported in specific financial statement captions in the prior year have been reclassified to conform to the fiscal 2015 presentation.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recent Accounting Pronouncements
	In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-05, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU clarifies the circumstances under which a cloud computing customer would account for the arrangement as a license of internal-use software. It is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. TimkenSteel is currently evaluating the impact of the adoption of this ASU on its results of operations and financial condition.
	In April 2015, the FASB issued ASU 2015-03, “Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” This ASU amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. TimkenSteel is currently evaluating the impact of the adoption of this accounting standard update on its results of operations and financial condition.
	In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” This ASU is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The amendments in this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted. The adoption of ASU 2014-15 did not affect the results of operations and financial condition of TimkenSteel.
	In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which provides guidance for revenue recognition. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. This ASU will supersede the revenue recognition requirements in Topic 605, “Revenue Recognition,” and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard will be effective for TimkenSteel in the first quarter of fiscal year 2017. Early adoption is not permitted. On April 1, 2015, the FASB voted to propose a one-year deferral of the effective date of ASU 2014-09, but to permit entities to adopt the standard on the original effective date if they choose. TimkenSteel is currently evaluating the impact of the adoption of this ASU on its results of operations and financial condition.

Inventory Disclosure [Abstract]
Inventory Disclosure [Text Block]	Inventories
	The components of inventories, net as of March 31, 2015 and December 31, 2014 were as follows:
		March 31,			December 31,
		2015			2014
	Inventories, net:
	Manufacturing supplies		$40.60			$38.50
	Raw materials	51.3			56.8
	Work in process	93.4			110.3
	Finished products	94.8			91.1
	Subtotal	280.1			296.7
	Allowance for surplus and obsolete inventory	(2.9		)	(2.9		)
	Total Inventories, net		$277.20			$293.80
	Inventories are valued at the lower of cost or market, with approximately 65% valued by the last-in, first-out (LIFO) method and the remaining inventories, including manufacturing supplies inventory as well as international (outside the United States), inventories valued by the first-in, first-out (FIFO), average cost or specific identification methods.
	An actual valuation of the inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations must be based on management’s estimates of expected year-end inventory levels and costs. Because these calculations are subject to many factors beyond management’s control, annual results may differ from interim results as they are subject to the final year-end LIFO inventory valuation.
	The LIFO reserve as of March 31, 2015 and December 31, 2014 was $80.7 million and $86.7 million, respectively. TimkenSteel projects that its LIFO reserve will decrease for the year ending December 31, 2015 based on lower anticipated costs, particularly scrap steel costs and anticipated lower inventory quantities, slightly offset by higher manufacturing costs.

	Total Long-Term Debt		$195.20		$185.20
	Credit Facility
	On June 30, 2014, TimkenSteel entered into a credit facility with JPMorgan Chase Bank, N.A., as administrative agent, PNC Bank, National Association, as syndication agent, Bank of America, N.A. and HSBC Bank USA, National Association, as co-documentation agents, and the other lenders and arrangers party thereto. The credit facility has a term of five years through June 30, 2019 and provides for a committed revolving credit line of up to $300.0 million. The credit facility includes an expansion option allowing TimkenSteel to request additional commitments of up to $150.0 million in term loans or revolving credit commitments, subject to certain conditions and approvals as set forth in the credit agreement. The credit facility provides a $50.0 million sublimit for multicurrency loans, a $50.0 million sublimit for letters of credit and a $30.0 million sublimit for swing line loans.
	The credit facility may be used for working capital and asset renewal and acquisition and is secured by a first priority lien on substantially all of the assets of TimkenSteel and its subsidiaries.
	TimkenSteel is required to maintain a certain capitalization ratio and interest coverage ratio as well as minimum liquidity balances as set forth in the credit agreement. As of March 31, 2015, TimkenSteel was in compliance with these ratios and liquidity requirements, as well as the additional covenants contained in the credit agreement. The credit agreement also provides the lenders with the ability to reduce the credit line amount even if TimkenSteel is in compliance with all conditions of the credit agreement upon a material adverse change to the business, properties, assets, financial condition or results of operations of TimkenSteel. Subject to certain limited exceptions, the credit agreement contains a number of restrictions that limit TimkenSteel’s ability to incur additional indebtedness, pledge its assets as security, guarantee obligations of third parties, make investments, undergo a merger or consolidation, dispose of assets, or materially change its line of business, among other things. In addition, the credit agreement includes a cross-default provision whereby an event of default under other debt obligations, as defined in the credit agreement, will be considered an event of default under the credit agreement.
	Borrowings under the credit facility bear interest based on the daily balance outstanding at LIBOR (with no rate floor), plus an applicable margin (varying from 1.25% to 2.25%) or, in certain cases, an alternate base rate (based on certain lending institutions’ Prime Rate or as otherwise specified in the credit agreement, with no rate floor), plus an applicable margin (varying from 0.25% to 1.25%). The credit facility also carries a commitment fee equal to the unused borrowings multiplied by an applicable margin (varying from 0.20% to 0.40%). The applicable margins are calculated quarterly and vary based on TimkenSteel’s consolidated capitalization ratio as set forth in the credit agreement. The interest rate under the revolving credit facility was 1.69% as of March 31, 2015. The amount available under the credit facility as of March 31, 2015 was $134.0 million.
	Revenue Refunding Bonds
	On June 1, 2014, Timken purchased, in lieu of redemption, the State of Ohio Water Development Revenue Refunding Bonds (Water Bonds), State of Ohio Air Quality Development Revenue Refunding Bonds (Air Quality Bonds) and State of Ohio Pollution Control Revenue Refunding Bonds (Pollution Control Bonds) (collectively, Bonds). Pursuant to an Assignment and Assumption Agreement dated June 24, 2014 (Assignment) between Timken and TimkenSteel, Timken assigned all of its right, title and interest in and to the loan agreements and the notes associated with the Bonds to, and these obligations were assumed by, TimkenSteel. Additionally, replacement letters of credit were issued for the Water Bonds and the Pollution Control Bonds. The Bonds were remarketed on June 24, 2014 (Remarketing Date) in connection with the conversion of the interest rate mode for the Bonds to the weekly rate and the delivery of the replacement letters of credit, as applicable. TimkenSteel is responsible for payment of the interest and principal associated with the Bonds subsequent to the Remarketing Date.
	All of TimkenSteel’s long-term debt is variable-rate debt and, as a result, the carrying value of this debt is a reasonable estimate of fair value as interest rates on these borrowings approximate current market rates, which is considered a Level 2 input.

	Prior to the spinoff, employees of TimkenSteel participated in various retirement and postretirement benefit plans sponsored by Timken. Because Timken provided these benefits to eligible employees and retirees of TimkenSteel, the costs to participating employees of TimkenSteel in these plans were reflected in the Unaudited Consolidated Financial Statements, while the related assets and liabilities were retained by Timken. Expense allocations for these benefits were determined based on a review of personnel by business unit and based on allocations of corporate and other shared functional personnel. All cost allocations related to the various retirement benefit plans have been deemed paid by TimkenSteel to Timken in the period in which the cost was recorded in the Unaudited Consolidated Statements of Income as a component of cost of products sold and selling, general and administrative expenses. Allocated benefit costs from Timken were funded through intercompany transactions.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	Earnings Per Share
	On June 30, 2014, 45.4 million TimkenSteel common shares were distributed to Timken shareholders in conjunction with the spinoff. For comparative purposes, and to provide a more meaningful calculation for weighted average shares, this amount was assumed to be outstanding as of the beginning of each period presented prior to the spinoff in the calculation of basic weighted average shares. In addition, for the dilutive weighted average share calculations, the dilutive securities outstanding at June 30, 2014 were assumed to also be outstanding at each of the periods presented prior to the spinoff. For the three months ended March 31, 2015 and 2014, 1.3 million and 0.2 million of equity-based awards, respectively, were excluded from the computation of diluted earnings per share because their effect would have been anti-dilutive.
	The following table sets forth the reconciliation of the numerator and the denominator of basic earnings per share and diluted earnings per share for the three months ended March 31, 2015 and 2014:

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	Segment Information
	TimkenSteel operates and reports financial results for two segments: Industrial & Mobile and Energy & Distribution. These segments represent the level at which the chief operating decision maker (CODM) reviews the financial performance of TimkenSteel and makes operating decisions. Segment earnings before interest and taxes (EBIT) is the measure of profit and loss that the CODM uses to evaluate the financial performance of TimkenSteel and is the basis for resource allocation, performance reviews and compensation. For these reasons, TimkenSteel believes that Segment EBIT represents the most relevant measure of segment profit and loss. The CODM may exclude certain charges or gains from EBIT, such as corporate charges and other special charges, to arrive at a Segment EBIT that is a more meaningful measure of profit and loss upon which to base operating decisions. TimkenSteel defines Segment EBIT margin as Segment EBIT as a percentage of net sales.
	TimkenSteel changed the method by which certain costs and expenses are allocated to its reportable segments beginning with the third quarter of 2014. The change reflects a refinement of its internal reporting to align with the way management now makes operating decisions and manages the growth and profitability of its business as an independent company subsequent to the spinoff from Timken. This change corresponds with management’s current approach to allocating costs and resources and assessing the performance of its segments. TimkenSteel reports segment information in accordance with the provisions of FASB Accounting Standards Codification 280, “Segment Reporting.” There has been no change in the total consolidated financial condition or results of operations previously reported as a result of the change in its segment cost structure. All periods presented have been adjusted to reflect this change.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Tax Provision
	TimkenSteel’s provision for income taxes in interim periods is computed by applying the appropriate estimated annual effective tax rates to income or loss before income taxes for the period. In addition, non-recurring or discrete items, including interest on prior-year tax liabilities, are recorded during the period(s) in which they occur.
		Three Months Ended March 31,
		2015			2014
	Provision for income taxes		$4.20			$17.20
	Effective tax rate	37.8		%	33.9		%
	The effective tax rate for the three months ended March 31, 2015 was higher than the U.S. federal statutory rate of 35% due primarily to U.S. state and local taxes and the effect of other permanent differences. This was partially offset by the tax benefit associated with non-U.S. earnings taxed at a rate less than the U.S. statutory rate.
	The effective tax rate for the three months ended March 31, 2014 was lower than the U.S. federal statutory rate of 35% due primarily to the U.S. manufacturing deduction. This factor was partially offset by U.S. state and local taxes.

Loss Contingency Accrual, Disclosures [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Contingencies
	TimkenSteel has a number of loss exposures that are incurred in the ordinary course of business such as environmental claims, product liability claims, product warranty claims, litigation and accounts receivable reserves. Establishing loss reserves for these matters requires management’s estimate and judgment regarding risk exposure and ultimate liability or realization. These loss reserves are reviewed periodically and adjustments are made to reflect the most recent facts and circumstances.
	Environmental Matters
	From time to time, TimkenSteel may be a party to lawsuits, claims or other proceedings related to environmental matters and/or may receive notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency and similar state or local authorities. TimkenSteel recorded reserves for such environmental matters as other current liabilities on the Unaudited Consolidated Balance Sheets. Accruals related to such environmental matters represent management’s best estimate of the fees and costs associated with these matters. Although it is not possible to predict with certainty the outcome of such matters, management believes that their ultimate dispositions should not have a material adverse effect on TimkenSteel’s financial position, cash flows, or results of operations.
