The steel is a widely used international air cooling hardening cold work die steel.Approved by electric furnace smelting and the electroslag solubility, high purity, better toughness, uniform organization, has good high temperature strength, toughness and resistance to high temperature fatigue performance, can withstand the temperature shock.
High hardness, high wear resistant uniform eutectic carbides, good toughness, not easy craze, > 62 HRC hardness after quenching.At 525 ℃ nitriding processing time for 20 h/h/h, 60 ammoniation layer depth of 0.25 mm / 0. 30 mm / 0. 35 mm, the surface hardness is 1250 hv,At 570 ℃ nitriding processing time is 2 h, nitriding depth 10 ~ 20 microns, the surface hardness is 950 hv.
