 Forging: 1.100 ~ 900 ℃ annealing: heating to 800-850 ℃, stay at this temperature in two to four hours in the furnace is allowed to gradually cool. Quenching: the first pre-heated to 550-600 ℃, time heated to 950 ℃, and then heated to a: 1,220 ~ 1250 ℃; b: 1,200 ℃ ~ 1230 ℃. Hardened in oil, but oil must be moisture 40-60 ℃ (a. general tools; b. form a complex type of tools needed toughness) Tempering: heating to 550-570 ℃, to stay at this temperature, then still air cooling, tempering must repeat the second hardness: hrc63 ℃ above. Uses: This high-speed steel tungsten steel, appropriate for manufacturing powerful cutting wear and impact resistance tools, advanced die, screw die, the more complicated to be resilient and shape tools, milling cutters, drills and other related products: 1.2080 tool steel, 1.2346 tool steel, tool steel 1.3343, 1.3243 tool steel, carbon structural steel 1.1210, 1.0037 carbon steel, cold work tool steel 2080, 2346 cold-working die steel and 3343 cold-working die steel, 3243 high-speed tool steel, 3247 high-speed tool steel, 1210 carbon steel, 0037 carbon steel, wear-resistant chromium steel 2080, 2346 Just wear high-chromium, 3343 toughness high-speed steel, 3243 high toughness high-speed steel, 3247 high cobalt toughness mold steel, 1210 high-quality carbon structural steel, plain carbon steel 0037, 2080 round, 2346 round, 3343 round, 3243 round, 3247 round, 1210 round, 0037 round, 2080 plates, 2346 plates, 3343 plates, 3243 plates, 3247 plates, 1210 plates, 0037 plates, cold-working die steel 2080 cold die steel, cold-working die steel 2346, 3343 high-speed tool steel, die steel 3243 high-speed, high-speed tool steel 3247, 1210 carbon steel, carbon structural steel 0037
