8Cr3 steel round bar
8Cr3 steel is formed by adding a certain amount of chromium into carbon tool T8. 8Cr3 steel has good quenching permeability and a certain room temperature, high temperature strength and formes small, uniform distribution of carbides.
8Cr3 die steel is usually used in the manufacture of hot, hot forging die, hot bending, etc.
