Die Steel

D2 steel is an air-hardening, high-carbon, high-chromium tool steel. It has high wear and abrasion-resistant properties. It is heat treatable and will offer a hardness in the range of 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening. D2 steel’s high chromium content gives it mild corrosion-resisting properties in the hardened condition. Cold-work tool steels include the high-carbon, high-chromium steels or group D steels. These steels are designated as group D steels and consist of D2, D3, D4, D5, and D7 steels. These steels contain 1.5 to 2.35% of carbon and 12% of chromium. Except for type D3 steel, all the other group D steels include 1% Mo and are air hardened. Type D3 steel is oil-quenched; though small sections can be gas quenched after austenitization using a vaccuum.
Applications • Knifes • Punches & dies • Thread rollers • Pressure casting moulds • Heavy duty press tools

D3 steel, also know as 1.2080 (Werkstoff), is an air hardening, high-carbon, high- D3 Tool Steel Bar chromium tool steel. It displays excellent abrasion/wear resistance and has good dimensional stability and high compressive strength.lt is heat treatable and will offer a hardness in the range 58-64 HRC. Due to its abrasion resistance in the hardened condition, D3 machining should be limited to finished grinding. D3 exhibits excellent stability in heat treatment, holding size almost as well as the air- hardening, high-carbon, high-chromium die steels such as D2. Cold-work tool steels which include D2, D3, D4, D5, and D7 steels are high-carbon, high-chromium steels. Apart from D3 steel all group D steels have 1% Mo and are air hardened. Type D3 steel is oil-quenched; though small sections can be gas quenched after austenitization using vacuum. As a result, tools made with type D3 steel tend to be brittle during hardening. Type D2 steel is the most commonly used steel among the group D steels. The D3 steels contain 1.5 to 2.35% of carbon and 12% of chromium.

Chromium hot-work tool steels are designated as group H steels according to the AISI classification system. This series of steels start from H1 to H19. The most commonly used chromium hot-work steels are H11, H12, and H13, which can be air-hardened in 150 mm thick sections. The steels are subjected to minimal distortion during hardening due to their balanced alloy content. The tools produced from chromium hot-work steels can be cooled using water without damage as these steels have low carbon and alloy contents.

P20 is an alloy tool steel which offers good machine ability even in the hardened and tempered (Brinell 300) condition. This steel gives an excellent polished finish and is one of the most widely accepted specifications for machine cut plastic molds and casting dies. P20 is often supplied in the hardened and tempered condition ready for machining. In this condition it gives excellent wear resistance but if maximum surface hardness is required for compression molding plastic dies or similar tools, the steel can be case hardened or nitride. For better machinability a higher Sulphur version P20S is available. For improved through hardenability in larger sections we also offer 1.2738 P20N.
