(Adds U.S. Steel statement, background)
Oct 15 (Reuters) - The United Steelworkers (USW) union said on Monday it reached a tentative agreement with U.S. Steel Corp covering 16,000 workers across the country.
The union has been negotiating with the Pittsburgh-based steelmaker for demands including higher wages.
Details about the new tentative agreement will be provided after its ratification, U.S. Steel said separately.
The union's collective bargaining agreement with U.S. Steel expired on Sept. 1 but union members had agreed to work under an extension as bargaining continued.
The previous agreement, reached during a downturn in the steel industry, included a three-year wage freeze, the USW said.
Earlier this month, the union said U.S. Steel had pulled back on some of its "worst proposals" during the talks. (Reporting by Sanjana Shivdas in Bengaluru; Editing by Sai Sachin Ravikumar)
