SS400 is a marking method for Japanese steel, which is actually Q235 steel in China. Q represents the yield strength of this material, followed by 235, which refers to the yield value of this material, around 235. And as the thickness of the material increases, its yield value decreases.
Due to moderate carbon content, good overall performance, and a good combination of strength, plasticity, and welding properties, SS400 steel plate is widely used. SS400 steel is often rolled into wire rods, round steel, square steel, flat steel, angle steel, I-beam, channel steel, window frame steel, and other steel sections, medium and thick steel plates.
SS400 steel is widely used in construction and engineering structures. Used for making steel bars or constructing factory buildings, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc.. It is also widely used as mechanical parts with low performance requirements.
