1: D3 steel introduction
AISI D3 cold work steel, also know as DIN 1.2080 (Werkstoff) and JIS SKD1, is a 12% chrome alloy steel. D3 cold work steelhas 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. Type AISI D3 cold works tool steel is oil-quenched; though small sections can be gas quenched after austenitization using vacuum. As a result, tools made with type D3 cold work tool steel tend to be brittle during hardening. Type D2 tool steel is the most commonly used steel among the group D steels. The D3 cold work steels contain 1.5 to 2.35% of carbon and 12% of chromium.

| Application |
AISI D3 Cold Work Steel has high strength, good hardenability and wear resistance. D3 is suitable for applications such as complex blanking and forming tools for long runs and for hard and abrasive materials.
Typical Applications:
- Highly stressed cutting
- Punching tools for thin sheets,
- Shear blades for cutting
- Profile rolls,
- Drawing and deep drawing tools,
- Stone processing tools,
- Knives for paper and plastics,
- Shear knives for thin sheets.
- Deep drawing,
- Pressure pads
- Highly wear-resistant plastic moulds.
