Tai'an Taiding Rigging Co., Ltd. summarizes the reasons for the corrosion of the chain.

     1. In the process of producing the chain, the enterprise did not carry out anti-rust treatment on the chain parts in the process and the finished chain after assembly in strict accordance with the requirements of cleaning and anti-rust regulations and oil seal anti-rust packaging. Such as chain contact with corrosive liquid or gas, etc.

     2. The quality of the anti-rust lubricating oil, cleaning kerosene and other products used by the enterprise in production cannot meet the requirements of the technical regulations.

     3. As the price of chain steel drops again and again, the material of chain steel gradually declines. For example, the content of non-metallic impurities in the steel is too high (the increase of the sulfur content in the steel reduces the corrosion resistance of the material itself), the metallographic structure deviation, etc. The source of chain steel used by the production enterprises is more complex, and the quality of the steel is even more mixed.

     4. The environmental conditions of some enterprises are poor, the content of harmful substances in the air is high, and the turnover site is too small, so it is difficult to carry out effective anti-rust treatment. Coupled with the hot weather, production workers violated anti-rust regulations and other phenomena.
