SS400 SS540 Carbon Steel Angle
JIS G3101 SS400 Steel SS540 Steel
SS400 steel is the most commonly used hot-rolled structural steel 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.
SS540 is a material grade and designation defined in
JIS G 3101 standard. JIS G 3101 is a Japanese material standard for hot Rolled steels
for general structural usage. The structural quality hot rolled SS540 steel is more reliable in
its tensile strength than SS400 steel.
