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.
Most building codes require a minimum of 4 in. (100 mm) of bearing. Considering all the building code dimensional requirements, the minimum wall thickness of a lined chimney to be used as a structural component is 10 in. (250 mm) consisting of: 1) 4-in. (100 mm) chimney wall (brick), 2) 2-in.(50 mm) of noncombustible material (brick), and 3) 4-in.(100 mm) bearing length (brick).ost building codes require a minimum of 4 in. (100 mm) of bearing.
