Description

42CrMo4 Alloy Steel is defined as a low alloy steel which has 1% Cr-Mo as strengthening alloy elements,commonly used in the manufacturing of different machine components. The steel is primarily known for its properties of high tensile strength and good wear resistance, which make it suitable for use in high-stress applications.

42CrMo4 is a kind of alloy steel with high hardenability, toughness and machinability. It has small temper deformation, high fatigue limit and resistance to repeated impact after quenching and tempering, available in the form of plates and bars.
