Information
Common heat treatment methods for chains: annealing, normalizing, quenching, tempering, carburizing, nitriding, carbonitriding, boronizing. The aging treatment has artificial aging treatment and natural aging treatment.
Normalizing, the steel is heated to Ac3 or above, and an operation of cooling in the air is taken out from the furnace after the heat preservation.
After quenching, the steel is heated to above Ac3 or Ac1, and after cooling, it is rapidly cooled in a coolant such as water or oil, and unstable structure has been obtained.
Tempering, reheating the quenched steel to a temperature below Ac1, heat treatment after cooling to room temperature.
Natural aging treatment, the aging phenomenon that occurs when the workpiece is placed at room temperature or under long-term storage under natural conditions is called natural aging treatment.
Artificial aging treatment, which adopts an aging treatment process of heating the workpiece to a higher temperature and performing aging treatment in a shorter time, which is called artificial aging treatment.
