FORGING:Heating for forging must be done slowly and uniformly. Soak through at F and reheat as often as necessary, stopping work when the temperature drops below 1700 After forging, cool slowly in lime, mica, dry ashes or furnace. D2 should always be annealed after forging. ANNEALING: Heat slowly to 1550 , hold until entire mass is heated through, and cool slowly in the furnace (40 F per hour) to about 1000 , after which cooling rate may be increased. Suitable precautions must be taken to prevent excessive carburization or decarburization. STRESS RELIEVING: When desirable to relieve the strains of machining, heat slowly to -1250& , allow to equalize, and then cool in still air (Strain Relieving). PREHEAT PRIOR TO HARDENING: Preheat slowly to 1350 and hold at this temperature until material is uniformly heated. HARDENING:After thorough preheating, heat to . Hold the work piece at the hardening temperature until it is completely and uniformly heated. QUENCHING: D2 steel is an air hardening steel and will develop hardness on cooling in still air. To avoid scaling and prevent decarburization of the work piece surface, controlled atmosphere or vacuum furnaces are recommended. If these furnaces are not available, pack hardening, salt baths or wrapping the piece in stainless steel foil will provide some degree of surface protection in the hardening process. 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 may be varied according to the desired hardness. If maximum hardness is desired, tempering should be in the range , but if a lower hardness is acceptable, tempering at F will give the optimum combination of hardness and toughness. standard AISI, ASTM, BS, DIN, GB, JIS Size 5-1800mm weight and dimensions according to customer

We are professional cold works D2 tool steel supplier for more than two decades. We supply AISI / ASTM A681 cold works D2 tool steels alloy steel materials in reliable quality and for attractive price for sale. We have deep knowledge of D2 tool steels chemical composition and properties. Contact us for any D2 tool steel materials demands. Cold Works D2 tool steel is a high carbon, high chromium tool steel (12% chrome) with extremely high wear resisting properties, heat treatable to 60-62 Rc. D2 steel is very wear resistant but not as tough as lower alloyed steels. D2 tool steel hardens in air with a low order of movement and offers a measure of corrosion resistance when polished. The high percentage of chromium gives it mild corrosion-resisting properties in the hardened condition. The mechanical properties of D2 are very sensitive to heat treatment. D2 steel is available in de-carb free rounds, flats, and squares, as well as ground flat stock and drill rod.

Detailed Product Description: Cold work tool steel D2/DIN1.2379 Soft annealing to HB230 Used for variou high precision,long lifetime cold work mould like punch mould 1.2379 Tool steel SKD11 Grade:D2/1.2379/SKD-11 Flate size:20-200*200-600mm Lenth:1-4m Round size:Dia20-300mm Length:1-6m Factory state:soft annealing to HB230 Application: Used for variou high precision,long lifetime cold work mould like punch mould,cold squeezing mould Other cold work tool steel are supplied, like AISI D3, AISI D6, AISI O1 etc. steel round bars, flat bars, plates, and block.

D2/1.2379 cold work tool steel is chrome-molybdenum-vanadium steel with big hardenability for hardening in oil and in air, especially high resistance to the wear (higher than by 1.2080), good cutting power, very good firmness in the pressure, lower toughness (but higher than by 1.2080). This steel shows good dimensional stability at the heat treatment, suitable for hardening to the secondary hardness (the possibility of nitriding). Further the steel is very difficult to sharpen, it works at the heat with difficulties and has a rather difficult workability in the annealed state. D2/1.2379 is suitable for making tools for cold cutting, i.e. all kinds of tools with the long durability for cutting on presses and punching of materials of smaller thicknesses and materials of high hardness (especially difficult-shape tools for cutting, e.g. transformer metal sheets and metal sheets from stainless steels), knives for plate shears for the sheet and strip steel up to thickness of 10 mm of sheared material, knives for wire cutting etc. Tools for mechanical working such as e.g. smaller girders and tools for drawing, all kinds of tools for transformation and punching of materials. Further the steel is suitable for simple and symmetric tools for pressing and pushing, tools for thread rolling, plain and profile rolls, swages and also for cold work. Cutting tools such as broaching thorns, profile knives and difficult-shape milling machines for lower cutting speeds and for treatment of nonmetallic abrasive materials. Further the steel is applied in the production of highly stressed molds and their components for working of plastic and powder substances, glass, porcelain and ceramic materials. By tools for crushing and grinding it is used for hammers of crushers and jaws for mild grinding and crushing.

High performance cutting tools for sheet upto 4mm thickness, trimming dies, blanking dies for paper and plastic, shear blades for cutting light gauge material, thread rolling dies , drawing, deep drawing, pressure pads and highly wear-resistant plastic moulds.
