Heat treatment

Heat treatment

Heat treatment refers to a material in the solid state, by means of heating, insulation and cooling to obtain the desired microstructure and properties of a metal thermal processing. Metal heat treatment is an important process in the manufacture of machinery, heat treatment generally does not change the shape and the overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece, or changing the chemical composition of the surface, to impart or improve the use of artifacts performance. Its characteristic is to improve the intrinsic quality of the workpiece, the metal workpiece having the desired mechanical properties, physical properties and chemical properties
