Advantage:
1. Marerial: we select good quality spring steel wire rod.
2. Surface treatment: advanced technology of shot blasting, 100% rubbed smooth, almost can do zero defects for the surface.
3. Quality assurance: Eddy current test online
4.Service life: Ultra fine martensitic structure which could improve the fatigue life of spring
5. Applicable Industriesl: Widely used in automobile, elevator, motorcycle, electric switches, high-speed rail, machinery. Meanwhile, we also can according to the customer's requests to produce many kinds of strength level for spring steel wire.
Mechanical property of steel wire in static level and Moderate fatigue level
