SS400 hot rolling plate

SS400 steel plate is actually the domestic Q235, but there are differences in specific indicators. Q235 has requirements for the content of C, Si, Mn, S, P and other elements, but SS400 only requires S and P to be less than 0.050. The yield point of Q235 is greater than 235 MP and the yield point of SS400 is 245 MPa.
 
Mechanical properties of SS400 steel:
Tensile strength (σb/MPa): 340-470
Yield point (σs/MPa): 235
Elongation after breaking (δ5/%): 24
Impact energy Akv -20 degrees: ≥27 J
 
Application of SS400 steel plate:
SS400 steel plate 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-thick steel plate. It is widely used in construction and engineering structures. SS400 hot rolling plate is used to make steel bars or to build factory buildings, high-voltage power transmission towers, bridges, vehicles, boilers, vessels, ships, etc. It is also widely used as mechanical parts with low performance requirements.
