Heat treatment process of claw hammer

Usually the heat treatment of claw hammer includes three processes of heating, heat preservation and cooling, but sometimes only two processes of heating and cooling are required. Under normal circumstances, these three processes are connected with each other without interruption. It can be roughly divided into direct heating and indirect heating. Charcoal, coal, liquid and gas fuels and electric heating are direct heating; molten salt or metal, and even floating particles can also be used for indirect heating.

When heating, the claw hammer is exposed to the air, and oxidation and decarburization often occur. This has a very negative effect on the surface properties of the parts after heat treatment. You must pay attention to the methods and methods to better enhance the product performance.
