Cr12MoV steel has high carbon content and chromium content, can form a large number of carbides and high-alloy martensite, so that the steel has high hardness and high wear resistance. At the same time, chromium also makes steel have high hardenability and tempering stability. Molybdenum increases the hardenability of steel and refines the grains. Vanadium… Read more Cr12MoV steel cold heading die cryogenic treatment
