SS400 is a Japanese standard carbon structural steel plate, which implements JIS G3101 standard, equivalent to Q235B in the national standard. It is equivalent to China's national standard Q235B, with a tensile strength of 400MPa. Due to its moderate carbon content, it has good overall performance, and its strength, plasticity and welding properties are well matched, making it the most widely used.

SS400 is often rolled into a coil or round steel, hot rolled steel sheet ss4oo, square steel, flat steel, angle steel bar ss4oo, I-beam, channel steel, window frame steel and other steel profiles, and medium-thick steel plate. A large number of applications in construction and engineering structures. Used to make reinforcing steel or construction of plants and shelves, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., also used as a large number of performance requirements are not too high mechanical parts; C, D-grade steel can also be used for some specialized steel.
1, In a 16mm steel plate specimen, the yield strength of the SS400 steel plate is 10Mpa higher than the Q235A yield strength.
2, Tensile strength and elongation are higher than Q235A.
3, SS400 steel plate is suitable for bridges, ships, and vehicles, Q235A steel plate is narrower than the SS400.
SS400 steel plate should have a variety of high-quality performance, in the use of the process is also outstanding, so the majority of users have been unanimously praised and recognized in the manufacturing industry, the frequent use and manufacturers continue to optimize and upgrade, and gradually SS400 steel plate has become one of the commonly used steel plate grades in the country.
