| Detailed Product Description： | SKD11 round spot sales specifications; (mm) 10-13-20-45-50-150-160-220-350 sheet stock Specifications: 13 * 32-610 - 75 * 32-610 skd11 of what material SKD11 kg how much the market price of the market? the SKD11 heat treatment method where the retail the SKD11 import material SKD11 domestic Fushun material SKD11 Shanghai factory in what position to buy quality and reliable materials find the Shanghai Hai Billiton integrity service allows you to buy more at ease [How to choose the right material Haituo 24 hours online to help you answer 】 Material Name: mold steel (haituojs) Material Grade: SKD11 material standard: JIS G4404: 2000 Materials and Heat Treatment Hardness: HRC58-60 SKD11 - high-carbon high-chromium alloy tool steel with high hardness wear resistance after heat treatment, and hardenability, good dimensional stability, suitable for making high precision and long life cold work die and of thermoset molding plastic mold. SKD11 characteristics: good toughness and resistance to high temperature fatigue properties can withstand temperature fusion, suitable for long-term work at high temperatures with good cutting and polishing performance SKD11 introduced (haituojs) is not greater than the thickness of 6mm sheet, efficient blanking die. Red contain mold and the pressure die scissors, inlaid blade, woodworking blade thread rolling die and wear slider cold heading die, thermosetting resin molding, senior gauge deep drawing forming, cold extrusion dies. The SKD11 use (for reference only) (haituojs). "Quenching and tempering" state quenching and cold treatment and tempering state (suitable for high precision and dimensional stability requirements) 3. "Quenching + tempering + nitriding treatment state (suitable for a high surface hardness requirements) cryogenic processing in order to obtain the highest hardness and dimensional stability, the mold immediately after quenching cryogenic -70 to -80 ° C and maintained for 3-4 hours , and then to return fire processing, cryogenic treatment tool or mold hardness than conventional heat treatment hardness 1-3HRC. The complex shape and size changes in the larger parts, cryogenic treatment the risk of cracking. 5. The nitriding treatment die or workpiece nitride treatment, the surface layer with high hardness and a certain corrosion resistance of hardened tissue. 6 at 525 ° C nitriding treatment, the surface hardness of about 1250HV, nitriding time of impact on the diffusion layer shown in the following table. Nitride time (hours) 203 060 nitriding depth (mm) 0.25 0.30 0.35 7 the 570 ℃ Tufftride, workpiece surface hardness of about 950HV. Usually soft nitriding treatment 2 hours, the depth of the hardened layer can be up to 10-20um the grinding die blanks or work in the low-temperature tempered condition, grinding, grinding crack prone. To prevent the occurrence of cracks should be taken to a small grinding feed rate repeatedly grinding, auxiliary good water conditions. Wire cutting complex shape or the size of the mold, to finally take line cutting is typically encountered when cracking occurred. To prevent cracking, it is recommended that the use of gas quenching and tempering at high temperatures, heat treatment to reduce stress, or embryos die cavity pre-processing. SKD11 chemical composition (haituojs)% C carbon silicon 1.40-1.60 Si 0.40 Mn Mn 0.50 Cr chromium 11.00-13.00 Mo molybdenum vanadium 0.80-1.20 V 0.30 P sulfur |
