Material name: Alloy tool steel
standard: GB/T 1299-1985 4Cr5MoSiV steel is air quench hardening hot work die steel, which is the H11 steel imported from the United States. Its performance and service life are higher than that of 3Cr2W8V steel. Suitable for aluminum alloy die-casting molds, tools and mandrels for hot extrusion and perforation, die forging hammer forging dies, press forging dies, high-speed precision forging dies and plastic dies, etc.; also used as aircraft, rockets, etc. Heat the structural parts with working temperature of 400～500℃. Carbon C: 0.33～0.43
Annealing, ≤235HB, indentation diameter ≥3.95mm, quenching, 790±15°C preheating, 1000±6°C (salt bath) or 1010±6°C (furnace control atmosphere) heating, heat preservation 5～15min, air cooling, 550±6 Temper at ℃.
