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.
From Wikipedia, the free encyclopedia. A514 is a particular type of high strength steel, which is quenched and tempered alloy steel, with a yield strength of 100,000 psi (100 ksi or approximately 700 MPa).The ArcelorMittal trademarked name is T-1.517 is a closely related alloy that is used for the production of high-strength pressure vessels. This is a standard set by the standards organization ASTM International, a voluntary standards development organizations that sets technical standards for materials, products, systems, and services.
