Oil tapered spring wire has excellent performance which is not available in high carbon spring and music wire. Oil tapered steel wire has superior strength and toughness. It will implement excellent elasticity, ductility, and better resistance against fatigue and deformation in various spring applications. Spring steel oil tapered wire provides spring makers of good coiling and relaxation under high tensile. Oil tapered wire is recommended to make the springs for repeated dynamic loads, including clutch springs. Smaller size oil tempered spring steel wire is used for making mattress springs, auto springs, etc.
