    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 reqSee more on chinesesteelgrades

    May 09, 2016 · The difference between annealing and tempering comes down to how it is treated. Annealing involves heating steel to a specified temperature and then cooling at a very slow and controlled rate, whereas tempering involves heating the metal to a precise temperature below the critical point, and is often done in air, vacuum or inert atmospheres.
