D2 Steel is more purified through vacuum degrassing. The spheroidized annealing makes it easily processed by shearing and cutting with no quenching cracks. It provides an superior abrasion resistance and toughness. It is widely used in less than 2mm thickness of flats, rolls, punches, dies for blanking, forming, trimming and thread rolling, shear knives, food-processing knives, and gages. Application:Cutting, punching, stamping tools, shear blades, thread rolling dies, cold extrusion dies, drawing and bending tools, flanging and straitening tools, fine cutting tools, deep drawing tools, drill bushes, coining dies, plastic moulds for abrasive polymers.

Plastic Mould Steels – P20 (pre-hardened steel) is the international general – purpose plastic mould steel after vacuum degassing and gas Electro – Slag – Remelting, it not only contains low sulfur and gas but also has good polishing performance P20 is typically sold in the pre-hardened condition after forged processing and ultrasonic detection without cracks. Typical applications include: Plastic injection mould Extrusion dies Blow molding mould Plastic Mould Steels – P20 is suitable for large and medium – sized and precise plastic mould parts, home appliances appearance molds, etc. Available size: Round steel bar 60-800mm Flat steel bar 25-400mm*200-800mm Surface condition: Black surface/ Grinded/ Machined Hardness of P20 Alloy Steel Bar: Q+T 50-54 HRC Characteristics: P20 alloy steel bar is with good toughness properties, easy to machine, better polishability than 1.2312, dimensional stability flame hardenable, good photoengraving properties. Applications: P20 alloy steel bar is used for plastic moulds, frames for plastic pressure dies, hydroforming tools.

H13 is the hot work tool steel with good toughness and high temperature resistance. It also owns excellent cutting and polishing performance. After electro-slag remelting, the quality is much better. This grade has found wide acceptance for extrusion dies for aluminum, zinc and copper, die casting molds, forging dies and hot shear blades. It is also an excellent steel for plastic. Available size: H13 steel round bar 60-800mm H13 steel flat bar 25-400mm*200-800mm Surface condition: Black surface/ Grinded/ Machined Hardness: Annealed HBS235 max Characteristics: H13 tool steel has good tenacity, hot tirdness nature and definite wearable;empty quenching under lower Ao shi ti temperature condition.small distortion after heat-treatment and so on. Applications: Tool steel h13 is used in hot forming tools,hot forging dies, pressure casting tools, hot shear knives, tools for plastic industry, hot punches and dies for blanking, hot extrusion dies for aluminium, tin and lead die casting.

D3 is characterised by a relatively high attainable hardness and good resistance. It exhibits excellent stability in heat treatment. Typical applications for D3 tool steel include forming rolls, drawing dies, forming powder compaction tooling and lamination dies.   Best for: High stressed cutting and punching tools for thin sheets, drawing and deep drawing tools, stone processing tools, knives for paper and plastics, shear knives for thin sheets, thread rolling dies. Applications: AISI D3 Tool Steel/Tool Steel D3/Flat Steel AISI D3 have high strength, good hardenability and wear resistance. AISI D3 Tool Steel/Tool Steel D3/Flat Steel AISI D3 is used in High performance cutting tools for steet upto 4mm thickness,trimming dies,blanking dies for paper and plastic ,shear blades for cutting light gauge materialthreat rolling dies,drawing,deep drawing,pressure pads and highly wear-resistant plastic moulds. Heat Treatment: Along with the furnace cooling after(850~870) °C× (3~4)h . (740~760)°C×(4~5)h,out air coldLow impact toughness and should avoid tempering at about 950~1150°C Surface Condition: Black surface/ Grinded/ Machined Hardness: HB250MAX
