説明
Chinese GB standard 45 steel is a quality carbon structural steel, the cold plasticity is common. Annealing and normalizing are slightly better than quenching and tempering, and have high strength and good machinability. A certain degree of toughness, plasticity and wear resistance can be obtained after appropriate heat treatment. Suitable for hydrogen welding and argon arc welding, not suitable for gas welding. Preheating is required before welding, and stress relief annealing should be performed after welding. China 45 steel = 45# steel = #45 steel 45 steel is a common material for shaft parts. After quenching and tempering (or normalizing), it can obtain better cutting performance, and can obtain high mechanical strength such as high strength and toughness. The surface hardness after quenching can reach 45-52 HRC.
