 Chemical composition% C Si Mn Cr W 2.05 0.3 0.8 12.5 1.3 1.D6 main features: ALCOAD6 is a tungsten-carbon, high chromium alloy steel, its features are: high compression wear polarity After the death of high strength hard surface hardness when hardened good hardenability, good stability, good resistance to temper softening ALCOA D6 steel because of its excellent wear resistance it is widely accepted engineering , it applies to long life mold and in the production process and lowest maintenance costs, with good economic returns. 6 The main purpose: cutting process: D6 material thickness (mm) Hardness (HB) less than 180 HRC 180 HRC die for: die cutting, fine blanking, punching, cut edge, cut, trimmed, cut cut less than 360-6256-58 truncated thin material, cold cut, hair chopped plastic knife for thin, car parks and other places panel cut truncation forging, trimming mold wood cutter, reamer, Broach 56-6058-60 58-6056-58 forming: processing the contents of the mold used: bending, stretching, deep drawing, beading, spinning molding. Tubes and profiles in type roll; cold drawing / finishing mode; die compaction of metal powder parts; cold complex mode with the female mold; for forming the mold; ceramics, bricks, tiles, grinding wheels, flat, wear plastic Molding; gauge, gauge, guide bushings, sleeves, knurled mode, sandblasting mouth, crushed red hammer; type anvil HRC 56-62 58-62 58-62 58-62 56-60 58-62 58 - 6256-6056-606 physical properties: temperature 20 ℃ 200 ℃ 400 ℃ Density Kg/m3 7700 7650 7600 Modulus N/mm2 193000 188000 173000 from the thermal expansion coefficient of 20 ℃ / ℃ - 11.0x10-6 10.8x10- 6 Thermal conductivity W / m ℃ 20.0 21.5 23.0 Specific heat J / kg ℃ 460 - - 6 compressive strength: compressive yield strength hardness HRC Rp0.2 MPa 62 2210 60 2110 55 1860 50 1620 45 1320 within
