Processing:
Steel wire can be heated through high-frequency power by means of oil tempering. The rapid heating treatment gives the steel wire high intensity. We use a high-precision temperature control system to ensure the steel wire heated stably and to ensure the consistency of material properties.

Oil Tapered Spring Wire

High Carbon Oil Tapered Spring Wire

Features and Applications:

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