JIS G3101 SS400\/SS490\/SS540 Cold Rolled Steel Plate<\/strong><\/b><\/h2>\n

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.\u00a0SS400 steel plate\u00a0itself 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.<\/p>\n
