Grade 50 is used in general plate applications when the plate will be riveted, bolted, or welded. Grade 50 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition, ASTM A572 Grade 50 is noted for its increased resistance to atmospheric corrosion..20. Tolerance under specified thickness .010. A 3/4 x 52 wide plate, for example, would have a tolerance range of .740/.780. Because of tolerances, i.e. thickness, flatness and camber, as well as the hot roll condition, ASTM A572 Grade 50 generally does not finish to specified thickness.
