- 60Si2MnA: A silicon-manganese spring steel containing 1.5-2.0% silicon, 0.6-0.9% manganese, and trace chromium. The alloy undergoes oil quenching at 870°C followed by tempering at 480°C, forming a fine-grained pearlitic structure with dispersed carbides.
- 50CrVA: A chromium-vanadium alloy with 0.8-1.1% chromium, 0.1-0.2% vanadium, and 0.5% carbon. It is processed via vacuum annealing at 850°C and tempering at 500°C, resulting in a tempered martensite matrix with improved toughness.

- Superior elastic recovery (≥98% after 10⁴ cycles) ideal for precision machinery valves and hydraulic seal preloaders
- Cost-effective solution for high-volume industrial applications like automotive transmission systems
- Excellent resistance to cyclic fatigue in moderate-load scenarios (5-200N axial force)
- Enhanced high-temperature stability maintains 90% load capacity at 300°C, suitable for aerospace actuators and turbine engines
- Higher impact toughness prevents brittle failure in shock-loaded environments such as off-road vehicle suspensions
- Vanadium alloying improves creep resistance, making it optimal for long-term static preload applications (e.g., bearing retention in wind turbines)
- Phosphate coating reduces friction by 25% in sliding contact applications
- Black oxide finish provides 48-hour salt spray resistance (ASTM B117) for general industrial use
- Nitriding increases surface hardness to 800 HV, extending wear life in dynamic applications
- Electroless nickel plating achieves 500-hour salt spray protection for marine and chemical environments
