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.
