SS400 hot rolling plate

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.
