Description
SS400 steel is the most commonly used hot-rolled structural steel (formerly known as SS41) in Japan, and is called general structural rolled steel in JIS G3101. SS400 material is cheap and versatile, and plays an important role in construction, bridges, civil engineering and mechanical equipment structures. Its appearance includes round steel, flat steel, steel plates, steel strips and profiles. SS400 Steel meaning: SS is the abbreviation of Steel Structure, 400 means that the tensile strength is ≥ 400 MPa. SS41 Meaning: 41 means that the tensile strength is 41kgf/mm2 or higher.
