Why do tire protection chains break during use
During use, there may be phenomena such as broken joints and broken rings due to:
- The material used in the casting process of the protective chain links does not meet the specified requirements.
- During the casting process, there are bubbles (commonly known as sand holes) or excessive impurities.
- There are problems in the process of chain heat treatment, and the heat treatment was not carried out according to the normal heat treatment specifications
- Before leaving the factory, tensile tests were not conducted one by one according to regulations.
