Filter Housings, which weighs 20.2kg, chooses 20# material, The forging of the product is essential in the process of heat treatment, the overall heat treatment process is the workpiece of heating to proper temperature, according to the material and workpiece size in different heat preservation time, and then slowly cooling, the purpose is to make the metal internal organization at or near equilibrium state and obtain good process performance and use of performance, or for further quenching organization.

Chemical heat treatment is to put the workpiece in the medium containing carbon, nitrogen or other alloy elements (gas, liquid, solid) heating, insulation for a long time, so that the surface of the workpiece into carbon, nitrogen, boron and chromium and other elements.

Other heat treatment processes such as quenching and tempering are sometimes carried out after the infiltration of elements. The main methods of chemical heat treatment are carburizing, nitriding and metal cementing.
