Heat Treatment 42crmo Steel Round Bar Performance Characteristics - China

42CrMo steel round bar is a commonly used alloy structural steel round bar material.

Performance characteristics:

High strength: After proper heat treatment, the tensile strength of 42CrMo steel round bar is ≥1080MPa, the yield strength is ≥930MPa, and it can withstand high stress.

High toughness: It has good toughness, impact work Aku≥63J, can withstand certain impact loads, and is not prone to brittle fracture.

Good hardenability: It can obtain uniform performance within a large cross-sectional size range, with small deformation during quenching and no obvious temper brittleness.

High fatigue strength: After quenching and tempering, 42CrMo steel round bar has a higher fatigue limit and resistance to multiple impacts, and is suitable for working conditions under long-term alternating stress.
