Precipitation hardening stainless steel, anti-relaxation and good stability, high temperature resistance,Has good corrosion resistance, is our new wave spring material.
Coil spring is one of the main car suspension components. It softens and kills vibrations received by a car body from the wheels when riding on uneven surfaces.
coil springs are made from finished steel in compliance with heating, winding, hardening, and tempering technologies standards. These coil springs also get surface reinforcement against surface fatigue. Materials and technologies used in coil springs production allow for car suspension life-time incensement in heavy road conditions
