Brief introduction of carbon structural steel SS400

SS400 is carbon structural steel, SS400 is a Japanese steel material, and the standard of SS400 steel is JIS G3101. SS400 is actually the domestic Q235, but there are differences in specific indicators. The content of elements such as C, Si, Mn, S, and P is required for Q235, but only S and P are required to be less than 0.050 for SS400. The yield point of Q235 steel is greater than 235 MPa and the yield point of carbon structural steel SS400 is 245 MPa.

Delivery status: Generally, carbon structural steel SS400 is delivered in a hot-rolled state, and the specific delivery status should be indicated.

SS400 mechanical properties: strength, hardness, plasticity, fatigue, impact toughness.
SS400 chemical properties: corrosion resistance, high temperature oxidation.
SS400 physical properties: density, melting point, thermal expansion, magnetic properties, electrical conductivity.
SS400 process performance: cutting performance, forgeability, castability, weldability.

Carbon structural steel SS400 SS400 use:
SS400 steel is often rolled into wire rod or round steel, square steel, flat steel, angle steel, I-beam, channel steel, window frame steel, etc., and medium and thick steel plates. It is widely used in construction and engineering structures. It is used to make steel bars or build factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also widely used as mechanical parts that do not require high performance.
