Carbon steel ASTM A36 S275JR Ss400 A283 grade C are the widely used carbon structural steels. Other than S275JR, the other mentioned steel grades are equivalent to each other.
Carbon steel ASTM A36 is one of the most widely used carbon steels, although the maximum carbon content of A36 steel is 0.29%, it is considered to be the mild steel (content of carbon ≤ 0.25%).
Carbon steel S275JR has huge usage for the structural building, manufacturing in the plant, machinery building, and in mining. Carbon steel S275JR is very versatile in nature.
Carbon steel SS400 is soft in hardness due to its low carbon content. Carbon steel SS400 is not recommended for use on main components with high strength, wear resistance or hardness. However, carbon steel SS400 has excellent weldability and machinability. Carbon steel SS400 is often used for welding structural parts, nuts, small parts, parts for auto & motor industry, etc.
Carbon steel A283 grade C is mainly used in heavy industry and oil plants for built steel tanks and vessels. Carbon steel A283 grade C is good in welding and economic for useage.
Carbon steel ASTM A36 S275JR SS400 A283 grade C are the most demanded steel sheet plates due to their unpredictable uses and aspects in the industrial world.
