spring steel wire can de divided into many kinds according different standards. According to the treatment status when leaving country, the spring steel wire can be divided into two classes.
The first class is the spring steel wire which has the mechanical properties that spring should have when it leave the factory. Such as the carbon spring steel wire, music wire and various oil quench-tempered spring steel wires and so on. This class of spring steel wire doesn't need quenching. It can obtain the required mechanical properties by thedestressing tempering. The mechanical designer should prefer to this class of spring steel wire, to remove the quenching crafts and reach the purpose of energy saving.
Another class of spring steel wire is non-oil quench-tempered spring steel wire, such as silicon-manganesespring steel wire, chrome vanadiumspring steel wire, chromessiliconspring steel wire and so on. This class of spring steel wire doesn't have the mechanical properties which the spring should have. When customers try to roll it spring, needs through the quench-temper processing. It is usually applied to the heat rounding spring with cross profile with large size. If you are going to order this kind of steel wire, please make out the requirements you need, such as annealing, high-temperature tempering and so on, or the manufacture will supply the steel wire without treatment.
