JIS G3101 SS400/SS490/SS540 Cold Rolled Steel Plate
JIS G3101 SS400 is a common carbon structural steel grade. Other grades of JIS G3101 are ss330, ss490 and ss540. Related product types include steel plate, steel plate, steel section, steel pipe, etc.
Description
JIS G3101 SS400/SS490/SS540 Cold Rolled Steel Plate
SS400 is a marking method for Japanese steel materials and a judgment standard, which is equivalent to Q235 steel. Ordinary structural steel in Japanese steel (JIS series) grades mainly consists of three parts: SS400-S means steel, the second S means “structure”, 400 is the lower limit tensile strength of 400MPa. SS400 steel plate itself not only has high strength, but also has certain comprehensive high-quality properties such as toughness, fatigue resistance, impact resistance, corrosion resistance, low temperature impact resistance, welding and easy processing. SS400 steel plates are widely used in construction and engineering structures.
