D6 steel is a high-carbon, high chromium tool steel alloyed with tungsten that is characterized by high compressive strength, high wear resistance, high surface hardness and good hardening stability. It is also called SKD2 steel and DIN 1.2436 steel. And D6 steel chemical composition and heat treatment information are below. Tool steels are primarily used to manufacture tools that can be used for machining metals, woods, and plastics. They are generally ingot-cast wrought products, and have the potential to be stable at elevated temperatures and withstand high specific loads. D6 Steel Application SKD2 steel chemical composition makes it become good tool steel in the industry. SKD2 steel is used for forming tools; molds for abrasive plastics and ceramics; long-run press tools; blanking and shearing tools for hard materials; stamping tools; scraping tools and etc. D6 Steel Round Bar Sheet Plate Heat Treatment Forging SKD2 tool steel is heated slowly and uniformly to 700�°C (1292�°F) and then more rapidly to 900-1050�°C (1652-1922�°F). Annealing SKD2 tool steel is then annealed at 800-840�°C (1472-1544�°F) and cooled. Hardness of the steel after annealing will be approximately 225 Brinell. Stress Relieving Stresses from SKD2 tool steel can be eliminated before hardening by heating up to 650-700�°C (1202-1292�°F), if machining operations have been heavy. The steel is then allowed to cool slowly. Hardening SKD2 steel is pre-heated slowly to 750-800�°C (1382-1472�°F) and thoroughly soaked. Heating is then continued till the final hardening of 950-980�°C (1742-1796�°F), followed by air or oil quenching. Tempering The SKD2 steel is heated uniformly and thoroughly at the selected tempering temperature. Double tempering can also be carried out with intermediate cooling to room temperature. Notice We have our own cutting and processing equipment. Specifications can be cut and customized according to your requirements. We are a professional special steel stockist and supplier with a high-quality stand for many years. Please contact us for any request of D6/SKD2 steels materials. Songshun Steel always with you.
D3 steel also knows as DIN 1.2080 and JIS SKD1, which is a 12% chrome alloy steel. JIS SKD1 steel has very high wear resistance against abrasive and adhesive wear due to the high volume of hard carbides in the steel matrix, medium toughness, dimensionally stable, high compressive strength, not secondary hardenable. D3 Steel Application 1.Highly stressed cutting 2.Punching tools for thin sheet 3.Blanking and forming dies 4.Forming rolls 5.Drawing and deep drawing tools 6.Slitting Knife 7.Stone processing tools 8.Pressure pads 9.Thermosetting plastic molding D3 Steel Round Bar Sheet Plate Heat Treatment Heat Treatment SKD1 steel requires hardening and tempering to achieve maximum properties. For maximum accuracy, the parts of SKD1 tool steel should be stress relieved after roughing operations. Stress should be relieved at 648 C (1200 F) for one hour and cooled slowly. Annealing Annealing of SKD1 steel needs to be done in a controlled atmosphere furnace. D3 steels should be heated thoroughly to 871 C (1600 F) and cooled slowly at a rate of not more than -6 C (20 F) per hour, until the furnace is black. Then the material should be removed and air cooled. Tempering The SKD1 steel should be cooled to room temperature and should be tempered immediately. The parts should be placed in the tempering furnace and increased slowly to the desired tempering temperature. Tempering for 1 hour per inch of thickness is required. Hardening SKD1 steel should be heated properly since it is very sensitive to overheating and if not heated maximum hardness cannot be achieved. The work should be directly placed in a furnace preheated to 954 C (1750 F) and soaked for 20-25 minutes, plus 5 minutes per inch of thickness, and then oil-quenched to harden it. Notice Other specifications are determined by daily stock. Customization is also acceptable. We are a professional special steel stockist and supplier with a high-quality stand for many years. Please contact us for any request of D3 tool steels materials. Songshun Steel always with you.
Heat Treatment DIN 1.2379 steels alloy should be preheated very slowly to 815 (1500 F) and the temperature can be increased to 1010oC (1850 F). Then held at 1010oC (1850 F) for 20 to 45 minutes and air-cooled (air quenched). Annealing Annealing of 1.2379 tool steels material should be done at 871 to 898 C (1600 to 1650 F) followed by slow furnace cooling at 4.4 C (40 F) per hour or less, after which cooling rate could be increased. At the same time, must do something to prevent excessive carburization or decarburization. Stress Relieving Heat it slowly to 1050 -1250 F, allow to equalize, and then cool in still air(Strain Relieving) Preheat Prior To Hardening Preheat slowly to 1350 -1450 F and hold at this temperature until steel 1.2379 steel material is uniformly heated. Hardening After thorough preheating, heat to 1800 -1850 F. Hold it at the hardening temperature until it is completely and uniformly heated. Quenching DIN 1.2379 steel tool material is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization on the surface, controlled atmosphere or vacuum furnaces are recommended. Parts should be allowed to cool to 150F, or to where they can be held in the bare hand, and then temper immediately. Tempering The tempering temperature on material 1.2379 steel may be varied according to the desired hardness. 1.2379 steels can be tempered at 204 C (400 F) for achieving Rockwell C hardness of 61 and at 537 °C (1000 F) for a Rockwell C hardness of 54. Compare Chinese Cr12Mo1V1 steel, American D2 steel, Japanese SKD11 steel, the chemical composition of them is the same, but the performance is very different. After heat treatment, the color of Cr12Mo1V1 is a little orange-red, and the deformation would be large. It is easy to fracture during use. And the hardness of D2 steel is higher than SKD11 steel, but the toughness is not better than SKD11 steel. SKD11 steel is light and smooth, with the best overall performance. D2 Steel Forging Heating for forging of AISI D2 tool steel should be done slowly and uniformly. Soak through at 1850 -1950 F and reheat as often as necessary, stopping work when the temperature drops below 1700 F(926 C). After D2 mold steel forging, cool slowly in lime, mica, dry ashes or furnace. D2 steel should always be annealed after forging. Songshun specialized in Special Steel for almost 20 years.
