Study on Thermal Fatigue Performance of Cold Work Roll Steel

Abstract:

Article Preview

Thermal stability and thermal fatigue performance tests of four kinds of cold work roll steels were done. There are indications that after isothermal 2~6 hours under conditions of 400°C~720°C, the best is 8Cr5SiMoV steel, its thermal stability grows up as isothermal time increase; the second is 8Cr4MoV steel; the worse are 8Cr5MoV steel and 9Cr3MoV steel; and all the thermal stability of four kinds of cold work roll steels are lower than 400°C. Thermal fatigue performance of four kinds of cold work roll steels are basically same as their thermal stability, i.e. the best is 8Cr5SiMoV steel, and the second is 8Cr4MoV steel.
