SKD11 Hitachi (SLD) Special cold mode alloy steel JIS G4404 AISI-D2 main ingredient:% C Si Mn Cr Mo the VPS 1.50 0.25 0.45 12.00 1.00 0.35 ≤ 0.025 ≤ 0.01 carbon the silicomanganese chrome-vanadium-molybdenum phosphorus sulfur steel characteristics: This steel high-carbon, high-chromium steel, high wear resistance and toughness, quenching resistance, heat deformation small. 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 generic mold steel, quenching SKD11 steel SKD11 mold steel SKD11 what materials the SKD11 the price SKD11 SKD11 heat treatment of the chemical composition the SKD11 features application SKD11 Hitachi cold work die steel
