The advantage of Oil Quenching Spring Steel Wire:
1. High yield ratio, small residual deformation of the spring.
2. Stable performance: with the disc less than conducive to coil spring and improve spring fatigue life.
3. High yield of spring-winding, which will help reduce cost.
4. Compared to tradition production methods, the oil tempered spring wire will reduce some working procedure.
