G80 Galvanized Lifting Alloy Steel Link Chain For Sale

The heat treatment of the lifting chain is an important necessary process, and its methods include: carburizing, nitriding, quenching, tempering, annealing, normalizing, carbonitriding, boronizing, etc. Heat treatment can bring key properties such as surface hardness and toughness to the chain. The following briefly introduces some common sense of heat treatment of lifting chains. Quenching is an extremely extensive heat treatment method in chain production, with high quenching efficiency and ability to bring a certain surface hardness to the chain. Annealing, normalizing, tempering: These heat treatment methods are to heat the steel and keep it warm for a certain period of time, without the need for liquid medium for cooling. Among them, the tempering process is carried out after quenching, which can reduce hardening, quenching stress and increase toughness.
