Heat the chain in the corresponding equipment to a certain temperature and keep it for some time , then add carbon-contained dielectric to carbonize the chain. It can improve the chain’s hardness and wear-resisting.
Heat the parts in the heat-treatment equipment to a certain temperature and keep it for some time , then in the light of the requirement cool it in different dielectric to increase its hardness.
Heat the quenched chain in the heat-treatment equipments with certain temperature and keep it for a certain time. I this way the chain’s tempering hardness can be reduced and quenching stress can be relived so as to improve its tenacity.
The oiled chain can avoid rust and looks more shinning.
The greased chain can avoid rust and looks more shinning. ( grease can be used if oiling is not convenient for maintenance )
