In view of the phenomenon of piston transverse crack in crushing hammer, the paper analyzes the transverse crack of piston, and puts forward a new heat treatment process of piston. The piston material was analyzed by using a hardness tester and a metallographic microscope. It is found that the material composition and metallographic structure at the location of the piston transverse crack failure are in line with the design requirements, while the hardness and hardened layer depth are lower than the design. Using Ansys, the maximum stress of the piston is
