SKD11 steel SKD11 mold steel SKD11 application of cold work die steel SKD11 Hitachi the SKD11 Hitachi brand (SLD) special the cold mold alloy steel JIS G4404 AISI-D2 main ingredient is what material the SKD11 price SKD11 chemical ingredient SKD11 the heat treatment SKD11 characteristics:% C Si Mn Cr Mo VPS 1.50 0.25 0.45 12.00 1.00 0.35 ≤ 0.025 ≤ 0.01 carbon silico-manganese chrome vanadium molybdenum phosphorus sulfur steel characteristics: This steel is a high carbon, high-chromium steel, wear resistance and toughness high resistance quenching, heat treatment deformation. Quenching: Preheat 700-750 ° C, and then heated to 1000-1050 ° C in still air cooling. Tempering: heating to 150-200 degrees, to stay at this temperature and then cooled in still air. Hardness: HRC58 annealing: heating to 800-850 ° C, stay at this temperature for 1-3 hours in the oven to cool gradually. Wrought: 1050 ° C-950 ° C Uses: apathy, roll forming, the scissors, the complex shape of the cold-pressed tools, plastic mold. Product Description: Hitachi Metals HITACHI (SKD11) is a common cold die steel wear resistance better. Quenching, and a small amount of quenching distortion. Its advantages: (1) a vacuum degassing refining and therefore extremely clean internal quality (2), (3) good machinability good hardenability, air cooling can be hardened without the fear of quenching crack (4) heat-treating the deformation is very small, quenching deviation is very small, the most suitable for the extremely good wear resistance of the accuracy requirements of the mold (5), the most suitable as a stainless steel or high punch die hard materials (6) toughness. types of steel: cold work die steel steel characteristics : wear good common mold steel, quenching
