Compared with spring, stainless steel spring is actually the same. Both of them are widely used in mechanical and electronic industries. The spring can produce large elastic deformation when loaded, and convert mechanical work or kinetic energy into deformation energy. After unloading, the deformation of spring disappears and returns to its original state, and the deformation energy is converted into mechanical work or kinetic energy. It can be used in the range of anti-corrosion, temperature resistance and non-magnetic.
The material of stainless steel spring must meet the standard of Yb (T) 11-83 Ministry of metallurgy. The commonly used materials are domestic stainless steel 304302301, 316316L, 3126.96.36.1990.420, Korean elephant brand, Kos Koryo, etc. T316 is recommended for high corrosion resistance and non-magnetic applications, but its mechanical properties are lower than those of t302 / T304. As one of the most widely used steel, t302 / T304 is the most commonly used stainless steel spring material because of its superior mechanical properties, corrosion resistance, heat resistance and low temperature strength. However, t631j1 / t631 is used for heat-resistant spring and spring with high tensile strength after heat treatment, but its corrosion resistance is worse than that of t302 / T304.
There are many kinds of material surface state, such as bare wire, resin plated spring and nickel plated spring wire. Stainless steel spring is divided into bright surface, semi bright surface and fog surface. Customers can choose according to the requirements of product precision and beauty.
Stainless steel spring has uniform and beautiful surface state, good formability, uniform elasticity, high plasticity, good fatigue strength, heat resistance and corrosion resistance. According to the shape, stainless steel spring can be divided into plate spring, spiral spring, ring spring, truncated cone scroll spring, disc spring and torsion bar spring. According to the mechanical properties, stainless steel spring can be divided into tension spring, torsion spring, bending spring and compression spring. The common cylindrical spring is widely used because of its simple manufacture and simple structure.
Generally speaking, the spring should have high elastic limit, fatigue limit, impact toughness and good heat and corrosion resistance, etc. the commonly used materials are referred to above. Generally, the diameter of spring wire is less than 20 mm by cold rolling method. Some springs need to be pressed or polished after being made, which can improve the bearing capacity of spring.
Whether it is non-magnetic or weak magnetic stainless steel spring, can be widely used in household appliances, electronics, civil, industrial and other products. It is an indispensable and widely used component in economic society and industrial society, which promotes the steady development of social economy.
