Board of Directors
United States Steel Corporation
600 Grant Street
Pittsburgh, Pennsylvania  15219-2800

Attention:  Mr. Thomas J. Usher, Chairman of the Board,
            Chief Executive Officer and President

To the Board of Directors:

I am Assistant General Counsel and Assistant Secretary of United States Steel
Corporation, a Delaware corporation ("USS"). I, or attorneys subject to my
supervision, have served as counsel to USS in connection with the proposed
issuance of up to 5,500,000 shares of common stock, par value $1.00 per share,
of USS (the "Shares") in connection with the United States Steel Corporation
Savings Fund Plan For Salaried Employees and in the preparation and filing with
the Securities and Exchange Commission of a Registration Statement on Form S-8
("Registration Statement") relating to such Shares.

As Assistant General Counsel and Assistant Secretary of USS, I am familiar with
USS's Certificate of Incorporation and By-Laws. I am also familiar with the
resolution adopted by USS's Board of Directors on April 30, 2002 authorizing the
issuance of the Shares. I have examined the Registration Statement and have
examined or caused to be examined such other documents, corporate records and
certificates of corporate officers and public officials as I have deemed
relevant or necessary to giving the opinion set forth below.

Based on the foregoing, I am of the opinion that the issuance of the Shares has
been approved by all necessary corporate action and that when the Shares are
sold they will be legally issued, fully paid and non-assessable.

I hereby consent to the filing of this opinion as an Exhibit to the Registration
Statement.

                                                     Very truly yours,

                                                     /s/ Robert M. Stanton

                                                     Robert M. Stanton
