After proper heat treatment or cold drawing hardening, high carbon steel wire has high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is acceptable, but welding function and cold plastic deformation ability is poor.
Because of the high carbon content, simple cracks occur during water quenching, so double liquid quenching (water quenching + oil cooling) is mostly used, and oil quenching is mostly used for small cross section parts. This type of steel is generally used after quenching by medium temperature tempering or normalizing or in the surface quenching state. Mainly used for manufacturing spring and wear-resistant parts.
Carbon steel wire is basically do not participate in alloying elements of high carbon steel wire, but also in the low cost of steel wire, hot and cold processing is outstanding, the use of a wide range of steel. Spring steel wire contains high carbon steel wire, high carbon steel wire is the spring steel wire in between.
All can do spring can be called spring steel wire, and high carbon is the highest carbon content. Features: WITH high strength and hardness, high elastic limit and fatigue limit (especially notched fatigue limit), cutting function is OK, but welding function and cold plastic deformation ability is poor.
