Description
This alloy is one of the cold work, high carbon, high chromium type tool steels. D2 is a deep hardening, highly wear resistant alloy. It hardens upon air cooling so as to have minimum distortion after heat treatment.
Applications
Used for long run tooling applications where wear resistance is important, such as blanking or forming dies and thread rolling dies, cutting tools, stamping, woodworking, moulding tools for plastics. Toughness better than in D3. Possibility of nitriding.
