​​The strong special-shaped spring is a type of spring that can operate in electronic, air-resistant, steam-resistant, water-resistant and other weakly corrosive media, as well as acid, alkali, salt and other chemical corrosive media. According to the nature of its stress, stainless steel springs can be classified into tension springs, compression springs, torsion springs and precision springs. They can be divided into disc springs, ring springs, spring sheets, helical springs, conical-topped vortex springs and torsion rod springs, etc. Ordinary cylindrical springs are widely used due to their simple manufacturing and can be widely used based on the type they are made of. The structure is simple. Generally speaking, springs should have a high elastic limit, fatigue limit, impact toughness, good heat resistance and corrosion resistance, etc. Common materials are as mentioned above. The cold winding method is usually used for spring wires with a diameter of less than 20 mm. The strong special-shaped spring also needs to undergo strong pressing or polishing after manufacturing, which can improve the load-bearing capacity and surface finish of the spring.

Description of the strong special-shaped spring: The main difference between the strong special-shaped spring and the conventional spring is that the spring itself is irregular, with bends and numerous complex angle designs. It is suitable for some special occasions.

​

The main strong-shaped special springs include: Variable-diameter helical springs: They are used in some special situations. The material of variable-diameter springs is generally of circular cross-section, and most of them can withstand compressive loads.

Sheet-type springs: These springs are made of spring-forming strip materials (or sheets). They are processed through corresponding molds on specialized equipment or general press processing machines. Such springs have a wide range of applications.

The commonly used materials include domestic stainless steel grades such as 304, 302, 301, 316, 321, 202, 201, 430, 420, etc.
