Ordinary structural steel with a tensile strength of 400 Mpa.This steel is the most widely used in JIS standard. Its use covers structures such as bridges, ships, vehicles, etc., in the shape of steel plates, steel bars and sections, almost all auxiliary materials for machinery and structures are used. SS400 is also soft in hardness due to its low carbon content. It is not recommended for use on main components with high strength, wear resistance or hardness. However, it has excellent weldability and machinability. It is often used for welding structural parts, nuts, small parts, parts for auto & motor industry, etc.
