Q235: can be used for a variety of abrasive handles and other unimportant abrasive parts. Once choose GCr15, 9SiCr, T8 and 45 steel, because the workpiece has bite die, sticky die phenomenon occurs, forging embryo is difficult to punch out from the die, resulting in plastic deformation, bending and fracture of the punch, the life is short.
1、Much used in architecture and engineering structure. C, D grade steel can also be used for some professional steel.
2、It can be used for various mold handles and other unimportant mold parts.
3、The Q235 steel is used as punch material, and it is used directly without tempering after quenching, and the hardness is 36~40HRC, which solves the phenomenon that the punch is broken in use.

Q235 and Q345 steels are commonly used in mechanical processing. The appearance is usually invisible. The color difference has nothing to do with the steel material, but the cooling method after rolling is different. Normally, the surface is red after natural cooling. If the method of quenching is adopted, and a dense oxide layer is formed on the surface, it will show black.
