SS400/A36/Q235B

Chemiscal composition：

Heat Treatment:

The quenching temperature is 950°C, heated by a salt bath furnace, and cooled and quenched by 10% NaCl brine.

The specialty of the steel:

Q in Q235 represents the yield limit of this material, and the following 235 refers to the yield value of this material, which is around 235MPa. And as the thickness of the material increases, its yield value decreases. Because the carbon content is moderate, the comprehensive performance is good, the strength, plasticity and welding properties are well matched, and it is the most widely used. Mainly used in construction and engineering structures. It is used to make steel bars or construct factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also widely used as mechanical parts that do not have high performance requirements.

Main uses:

Q235 Low-Carbon Steel is widely used in construction and engineering structures. It is used to make steel bars or construct factory building frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc. It is also widely used in mechanical parts that do not have high performance requirements. Grade C and D steel can also be used as some professional steel；

Can be used for various mold handles and other unimportant mold parts；

Q235 steel is used as the punch material. It can be used directly without tempering after quenching. The hardness is 36~40HRC, which solves the problem of the punch breaking during use；
