| Abstract: | The influence of prenitriding diffusion of nitrogen atoms and delaying Quenching temperature on the miCrohae, hardness and substructure of steel 60SiZMn has been studied usillg optical microscope, hardness testers and trausmission electron microscope(TEM).The test results show that the service life of piercing punch made of steel 60Si2Mn for hexagonal nut with strength and toughening treatment is increased by more than 2 times. |
