Problems solved by technology

[0002] With the increasing requirements for corrosion-resistant springs in various industries, especially for a series of requirements such as high load, light weight, high strength, high toughness, good corrosion resistance and welding performance, the application range of springs is increasing. Wider, it plays a vital role in all walks of life, because the surface of the spring is easy to wear during long-term use, and the surface of the spring is easily oxidized, which reduces the service life of the spring and increases the cost, and the spring is in a harsh environment. It is easy to corrode, which reduces the service life of the equipment, increases the cost, reduces the work efficiency, and easily leads to equipment failure
