Stainless steel spring according to the nature of force, the stainless steel spring can be divided into stretch spring, compression spring, torsion spring and bending spring, according to the shape can be divided into disc spring, ring spring, spring, coil spring, truncated cone coil spring and torsion spring.

Because of the simple manufacture of ordinary cylindrical spring, and can be made according to the loading situation of various types, simple structure, so it is widely used. Spring in general should have a high elastic limit, fatigue limit, impact toughness and good resistance to heat and corrosion, such as the material used for reference. Commonly used spring wire diameter below 20 mm with cold coil method, stainless steel spring in the production of strong pressure or polishing treatment, can improve the bearing capacity of the spring and surface finish.
