1. Annealing
Annealing is the heating of the steel spool to the proper temperature and then the slow cooling of the steel casing to or near equilibrium.
2. Normalization
Normalizing is to cool the steel spool after reaching the right temperature, the effect of normalizing is similar to annealing, and it is usually used to improve the cutting properties of the material, and sometimes it is also used for low requirements for certain parts as a final heat treatment.
3. Quenching
Quenching is a rapid cooling process after heating a workpiece in a quenching medium of water, oil or other organic salts and organic water. Steel hardens after quenching, but at the same time becomes brittle.
4. Tempering
Tempering is done to reduce the brittleness of the steel. The quenched steel is kept at 650 °C above room temperature for a long time and cooled again, a process known as tempering.
