SS400 is basically equivalent to Q235 in China (equivalent to Q235A), but there are differences in specific indicators. Q235 requires the content of elements such as C, Si, Mn, S and P, but SS400 only requires that S P is less than 0.050 and the yield point of Q235 is greater than 235 MPa, and the yield point of SS400 is 245MPa SS400(Steel for General Structure) means that the tensile strength is greater than 400MPa general structure with steel Q235 means that the yield point is greater than 235MPa ordinary carbon structural steel,SS400 standard number is JIS G3101 Q235 standard number is GB/T700.
SS400 is a way of marking Japanese steel, in fact, the domestic Q235 steel is a kind of steel material Q represents this kind of material yield degrees, at the back of the 235, is refers to the material yield value, at around 235 And with the increase of the thickness of the material and reduce the yield value Because carbon is moderate, has good comprehensive performance, plasticity and bonding strength performance is better, the most widely use Often rolled into wire rod or round steel square steel flat steel Angle I-steel channel steel window frame steel and other steel, thick steel plate is widely used in construction and engineering structure to make steel bars or to build workshops, buildings, high-voltage power transmission towers, Bridges, vehicles, boilers, vessels and so on, but also a large number of mechanical parts of the performance requirements are not too high C D grade steel can also be used for some special industry steel
