Information
Common heat treatment methods for suspension chains: annealing, normalizing, quenching, tempering, carburizing, nitriding, carbonitriding, and boronizing. The aging treatment has artificial aging treatment and natural aging treatment.
   Annealing, the workpiece is heated to 30-50 degrees above Ac3, after holding it for a certain period of time, it is slowly cooled down to 500 degrees with the furnace and then cooled in the space.
  Normalizing is an operation in which steel parts are heated to above Ac3 or Acm, and after heat preservation, the chain is suspended and taken out of the furnace and cooled in the air.
   Quenching, heating the steel parts to above Ac3 or Ac1, and then rapidly cooling them in a cooling liquid such as water or oil after heat preservation, and an unstable structure has been obtained.
   The suspension chain is tempered, and the quenched steel is reheated to a temperature below Ac1, and then cooled to room temperature after heat preservation.
  Natural aging treatment, the aging phenomenon that occurs when the workpiece is stored at room temperature or under natural conditions for a long time, is called natural aging treatment.
  Artificial aging treatment, using the aging treatment process that heats the workpiece to a higher temperature and hangs the chain to a higher temperature, and performs aging treatment in a shorter time, called artificial aging treatment
