European Standard 42crmo4 Steel Hardness With Performance Relationship - China

42CrMo4 steel hardness and performance relationship

Hardness and wear resistance: The higher the hardness, the better the wear resistance.

For example, 42CrMo4 steel that has been surface hardened has a high surface hardness and is suitable for manufacturing parts that require high wear resistance, such as gears and shafts.

Hardness and toughness: Increased hardness usually reduces the toughness of the material.

42CrMo4 steel after quenching and tempering has achieved a good balance between hardness and toughness and is suitable for parts that are subjected to alternating stress.

Hardness and machinability: When the hardness is low (such as in the annealed state), the material has good machinability; when the hardness is high, the machining difficulty increases.
