heat treatment

Many metals last an important heat treatment process is the simplest method is the annealing heat treatment, it is billet reheating molding that high temperature to remove stress and homogenization of alloy composition, heat treatment is a concern in cooling rate and the relationship between the annealing temperature, rapid cooling after quenching, usually used for a medium carbon steel for the performance of the high hardness.It can be 1000 degrees by quenching in oil or water, get martensite.Different heat treatment can be formed in the steel micro facies, martensite was formed by steel cooling is blocked, it is a one phase.
