The specific application of SS400 steel plate: due to the moderate carbon content, the comprehensive performance is good, and the strength, plasticity and welding properties are well matched, and it is widely used. It is widely used in construction and engineering structures. SS400 steel plate is also used to make steel bars or to build factory buildings, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also widely used as mechanical parts that do not require high performance. C, D grade steel can also be used as some professional steel.
The specific indicators of SS400 steel plate and Q235 steel plate are different. Q235 requires the contents of elements such as C, Si, Mn, S, and P, but SS400 only requires that S and P be less than 0.050.
The yield point of Q235 stee plate is greater than 235 MPa, while the yield point of SS400 steel plate is 245 MPa. SS400 (steel for general structure) means general structural steel with a tensile strength greater than 400MPa. Q235 steel plate means ordinary carbon structural steel with a yield point greater than 235MPa. The standard number of SS400 steel plate is JIS G3101. The standard number of Q235 steel plate is GB/T700.
