Stainless steel spring material related understanding

Compared with springs, stainless steel springs are actually the same. Both are elastic components widely used in the mechanical and electronic industries. The spring can produce greater elastic deformation when loaded, converting mechanical work or kinetic energy into deformation energy, and the deformation of the spring disappears and returns to its original shape after unloading. , Transforming deformation energy into mechanical work or kinetic energy. It is suitable for the range of anti-corrosion, temperature resistance, non-magnetic, etc.
Generally speaking, springs should have high elastic limit, fatigue limit, impact toughness and good heat resistance and corrosion resistance, etc. The commonly used materials are referred to above. Commonly used spring wire with a diameter of less than 20 mm is cold-rolled. Some springs need to be pressed or polished after they are made to improve the load-bearing capacity of the spring.

Whether it is non-magnetic or weakly magnetic stainless steel springs, they can be widely used in home appliances, electronics, civil, industrial and other products. It is a component that is indispensable and widely used in both economic society and industrial society, and promotes the steady development of social economy.

Stainless steel spring materials must meet the standard YB(T)11-83 Ministry of Metallurgy Standards. Commonly used materials: domestic stainless steel 304,302,301,316,316L,321.202.201.430.420, and imported Korean elephant brand, KOS Korea Corporation, etc. T316 is recommended for high corrosion resistance and non-magnetic applications, but its mechanical properties are lower than T302/T304. T302/T304 is the most widely used steel because it contains Ni and has superior mechanical properties, corrosion resistance, heat resistance, and low temperature strength. It is the most commonly used stainless steel spring material. T631J1/T631 are used for heat-resistant springs and springs with high tensile strength after heat treatment, but their corrosion resistance is worse than T302/T304.

There are also many options for the surface condition of the material, such as bare wire, resin-plated spring, and wire nickel-plated spring wire. Customers can choose according to the requirements of product precision and beauty.

Stainless steel springs have uniform and beautiful surface conditions, good formability, uniform elasticity, high plasticity, fatigue resistance, heat resistance and corrosion resistance. Stainless steel springs can be divided into leaf springs, spiral springs, ring springs, truncated cone scroll springs, disc springs, and torsion bar springs. According to the nature of the force, stainless steel springs can be divided into tension springs, torsion springs, bending springs, and compression springs. Ordinary cylindrical springs are the most widely used because they are simple to manufacture and can be made into various types according to the load conditions, and their structure is simple.
