According to the purpose and function, it can be divided into transmission chain for power transmission, material transmission chain, traction chain for traction and lifting, and special special chain with special function and structure for special mechanical device. The shaft and sleeve of the Steinless steel chain shall be surface hardened and can be connected together under high pressure, so as to withstand the pressure generated by the load and the gear action transmitted by the roller of the chain.

In addition to classification according to use and function, it can also be classified according to pitch, roller diameter and width between inner chain plates. However, these classification methods directly determine the shape and width of sprocket wheel teeth, so they can be simply referred to as classification according to gear unit size. It can also be classified according to different structures. In the same kind of products, it can be classified according to the shape of the components that make up the chain, the meshing parts and parts with the chain, the size ratio between parts, etc.

Steinless steel chain is basically a labor-intensive product, and many developed regions have turned to production in developing regions, which brings new opportunities for China's chain to expand exports. Chain manufacturing capacity is the decisive factor of chain manufacturing industry, and the core of chain manufacturing strength is the process degree of chain manufacturing.

The degree of chain manufacturing technology largely depends on the degree of chain consumption expertise. It is precisely because of these characteristics of the stainless steel chain that it is widely used in situations requiring high and low temperature work.
