1. 40Cr belongs to medium carbon alloy structural steel, and the addition of chromium (Cr) element significantly improves the hardenability, wear resistance, and tempering softening resistance of the material. Its chemical composition and mechanical properties strictly follow the YB/T 5035-2020 standard, especially suitable for manufacturing automotive half axle bushings that can withstand high torque and high impact loads.
2. Core advantages:
High strength: After quenching and tempering treatment, the tensile strength is ≥ 980MPa and the yield strength is ≥ 785MPa, far exceeding ordinary carbon steel.
Anti fatigue: With a fatigue life of over 500000 cycles, it is suitable for long-term use in complex road conditions.
Easy to process: Through hot rolling, cold rolling, and precision heat treatment processes, high-precision forming can be achieved (wall thickness deviation within ± 0.3mm).
