1.2085 Characteristics of die steel
1.2085 die steel according to is produced according to the German standard die steel, usually the case pre-hardened (tempered) state delivery, pre-hardened hardness HB280-HB325. scientific moderate adjustment of S content, can improve the steel's easy cutting processing performance, that is, the sulfur system easy cutting die steel.

2, material characteristics: corrosion-resistant, high-alloy, pre-hardened mold steel; can also be used as corrosion-resistant plastic mold; excellent corrosion resistance can reduce mold maintenance workload; can be nitrided, hard chromium plating; Changxiang Special Steel recommends that the steel is not used as a mold insert. 3, process route: EF + LF + VD → hot forging → annealing → milling → pre-hardening → processing mold frame or finishing → real air quenching → surface pressure processing or electroplating or chemical Heat treatment.4、Steel crystallization temperature: 1470℃-1360℃5、Lower than the final forging temperature austenite (A) relative amount.

3, heat treatment quenching and hardening temperature: 1000 ℃ -1030 ℃, cooling medium: oil. Vacuum heat treatment can be gas quenching, quenching surface hardness HRC48.
