What is the Common 42CrMo4 Heat Treatment Condition ?

DIN 42CrMo4 steel material is one popupar alloy steel. It’s widely used in mechanical industry or oil industry. Because 42CrMo4 steel could be heat treated to achieve different strength requirement to suit different environments. But What is the Common 42CrMo4 Heat Treatment Condition ?

DIN 42CrMo4 steel is usually supplied as rolled, annealed or Q+T condition.

• When there is no special strength or hardness requirement, 42CrMo4 is supplied as rolled condition.
• When low hardness is required, 42CrMo4 steel is to be supplied as annealed condition.
• When high yield strength and tensile strength is required, 42CrMo4 could be heat treated by quenching and tempering (Q+T).
