42CrMo4 material properties are high tensile strength, stress resistance, wear and tear resistance, and hardness. In quenched and tempered conditions, 42CrMo4 has excellent wear and tear resistance. 42CrMo4 hardness is more as compared to other steel grades. ​42CrMo4 finds its application in industries such as the aircraft industry, automobile industry, automotive industry, defence industry, etc. Heat Treatments such as normalizing, tempering, quenching, etc can be applied to 42CrMo4. It is used to make chains, screws, gears, arms, rollers and various other machine parts.

42CrMo4 Chemical Composition
The Chemical Composition of 42CrMo4 contains a medium level of carbon content of 0.38 - 0.45 %. The material has an Mn content of 0.6 - 0.9 % which imparts hardness to the material. The contents of P is reduced to 0.025% and S is reduced to 0.035 % max as excess content of P and S can damage the quality of steel and can cause the alloys steel to break at low stresses. There is a high Chromium content of 0.9-1.20 % which imparts extra hardness to the material.
