EN 1.7225 chromium-molybdenum alloy steel 42CrMo4 and 42CrMo4 equivalent material are usually used after quenching and tempering. Then the steel 42CrMo4 will enjoy high intensity and high hardenability.
EN 1.7225 chromium-molybdenum alloy steel 42CrMo4 and 42CrMo4 equivalent material has better performance than 34CrMo4 steel due to higher carbon and chromium content, which contributes to its higher strength and hardenability.
