1. The mould steel heat treatment generally consists of three parts: ordinary heat treatment, surface heat treatment and deformation heat treatment.
2. Common heat treatment includes annealing, normalizing, quenching and tempering.
3. Annealing and normalizing we commonly known as preheat treatment, quenching and tempering we call final heat treatment.
4. Mould steel is used to make steel for cold stamping die and hot forging die.Molds are the main processing tools for manufacturing parts in industrial sectors such as mechanical manufacturing, radio meters, motors and electrical appliances.Mold quality directly affects the pressure processing technology, the precision of the product yield and quality of the service life of the production cost, and the quality of the mould and except by reasonable structure design and machining precision, mainly by the influence of die material and heat treatment.
