Ultra‑High Strength
After oil quenching at ≈ 850 °C and tempering at ≈ 450 °C, 50CrV achieves tensile strength ≈ 1,350‑1,650 MPa and yield strength above 1,200 MPa, supporting severe load use
Excellent Toughness & Shock Resistance
Its vanadium‑refined martensite microstructure delivers impact toughness of 8–30 J in many cross‑sections, ensuring reliable performance under dynamic loading
Outstanding Fatigue Life & Resilience
The combination of high hardenability and a high yield ratio yields resilient spring behavior and long fatigue life under cyclic stress
Grain‑Refined Hardenability & Excellent Forging Workability
Vanadium promotes fine martensite grains for low distortion during quenching and consistent quality even in large forged sections
Automotive Suspension & Valve Springs
Widely used in car suspension systems and engine valve springs, offering excellent fatigue resistance under cyclic loads.
Heavy-Duty Industrial Springs
Applied in machinery requiring high-load compression, torsion, and shock springs due to its superior strength and toughness.
Thermal System Safety Components
Ideal for safety valves, piston rods, and mechanical parts operating under high temperatures up to 300°C with stable elasticity.
High-Strength Shafts, Pins & Gears
Suitable for shafts, axles, crankpins, and gear components that demand high wear resistance and long-term mechanical reliability.
