Aerospace Grade High Torque Disc Spring Chromium Vanadium Alloy Disc Spring Washer
Designed specifically for environments where rotational forces exceed 10,000 Nm and operational temperatures range from -50°C to 250°C, this disc spring delivers unwavering performance under relentless stress.
Forged from aerospace-grade chromium-vanadium alloy (ASTM A231 standard) and subjected to a proprietary dual-stage heat treatment process:
- Vacuum quenching at 860°C followed by tempering at 450°C
- Tensile strength of 2000 MPa
- Rockwell hardness of HRC 52-54
- Exceptional resistance to plastic deformation and fatigue
Maintains 95% of initial torque capacity even after 100,000+ cycles in accelerated life testing—significantly outperforming conventional springs that degrade after just 10,000 load cycles.
Features a precision-engineered dished profile with 15° conical angle and optimized 1:8 thickness-to-outer-diameter ratio for uniform torque distribution across mating surfaces.
- Reduces localized stress by up to 35% compared to flat washers
- Edge-beveled design minimizes stress risers
- Corrosion-resistant zinc-nickel coating (1000+ hours salt spray resistance per ASTM B117)
Backed by finite element analysis (FEA) validation and ISO 16232-3 compliance, ensuring consistent performance where failure is not an option.
