Classification of heat treatment process for metallic materials.(cnc machining metal parts ,precision steel machining)

The process of metal heat treatment can be divided into three categories: overall heat treatment, surface heat treatment and chemical heat treatment.According to different heating medium, heating temperature and cooling method, each category can be divided into several different heat treatment processes.Different heat treatment processes can be used for the same metal, which can obtain different tissues and thus have different properties.Steel is the most widely used metal in industry, and the steel microstructure is the most complex, so there are many kinds of steel heat treatment process.The overall heat treatment is to heat the workpiece as a whole and then cool it at the appropriate speed to obtain the required metallographic structure to change the metal heat treatment process of its overall mechanical properties.The overall heat treatment of steel has four basic processes: annealing, normalizing, quenching and tempering.
