Q235 Q345 U Channel Steel

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.

Q345: is a common material for shaft parts, it is cheap after tempering (or normalizing), can get better cutting properties, and can get higher comprehensive mechanical properties such as strength and toughness, and the surface hardness after quenching can reach 45~52HRC.

Q345 has good comprehensive mechanical properties, low temperature performance, plasticity and weldability, used for low and medium pressure containers, tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures bearing dynamic loads, mechanical parts, building structures, general metal structural parts, hot rolled or normalized state use, can be used for a variety of structures in cold areas above -40 ℃.
