The U.S. Department of Defense has restored a rule mandating that steel armor plate purchased by the U.S. military be made in the United States, a move that will benefit Ohio steel companies.

Ohio Sen. Sherrod Brown, in announcing the decision Wednesday, said Cleveland’s ArcelorMittal and Cliffs Natural Resources, as well as Nucor in Marion, Ind, stand to gain. All are involved in the production of armor plate.

“This is a win for our military and for American companies like ArcelorMittal, Cliffs, and Nucor, that make steel for our military right here in the United States,” Brown said. “We know how to make steel armor plate here in America, and there’s no reason why countries like China and Russia should be making the steel used in our military’s vehicles and equipment.”
