The performance and heat treatment process of cold-working die steel have a decisive influence on the service life of the die. The properties of cold work die steel mainly include wear resistance, toughness, strength, fatigue resistance and bite resistance. The performance of heat treatment process mainly includes hardenability, hardening capacity, tempering resistance, overheating sensitivity, oxidation decarburization tendency, quenching deformation and cracking tendency, etc. The performance and heat treatment research progress of typical cold-working die steel and new cold-working die steel are described in order to improve the service life of the die.
