What material is 42 chrome molybdenum steel

42CrMo steel is an ultra-high strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering treatment, and good low temperature impact toughness.

The difference between 42 chrome molybdenum steel and chrome molybdenum vanadium:

Chromium-vanadium steel is an alloy tool steel with chromium-vanadium alloy elements added. The hardest metal element is chromium, so the hardness of chromium-vanadium steel after heat treatment is above 60HRC, and it has good wear resistance under specific working conditions. Molybdenum vanadium steel is the addition of molybdenum vanadium to the steel, which greatly improves the hardness of the steel without affecting the toughness and corrosion resistance of the steel. Chromium molybdenum vanadium combines the advantages of the first two and is a common and durable cold stamping metal die steel.
