A633 Carbon Steel Coil
Product Description
A633 steel has four grades of A, C, D, and E. The thickness of grade C can reach 4 inches and the thickness of grade E can reach 6 inches. ASTM A633 steel specification is based on the standard specification for standardized high-strength low-alloy structural steel coil, which requires high notch toughness under low temperature conditions.

A633 carbon steel coil is a normalized high-strength low-alloy structural steel coil used for welded, riveted or bolted structures. This material is suitable for use at lower ambient temperatures where the required notch toughness is better than that expected for rolled materials of comparable strength. The material has good austenite grain size and should be normalized by heat treatment. Its chemical composition should be determined by thermal analysis. Tensile testing should also be performed. A633 steel coils are usually used in manufacturing plants, general construction and various types of engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, and various cranes for mining and various engineering constructions.
