D2 Tool Steel Bar is a high-carbon, high-chromium cold work tool steel widely known for its exceptional wear resistance and dimensional stability. As one of the most popular tool steels in the industry, D2 Steel offers superior hardness and abrasion resistance, making it ideal for long-run tooling applications. It conforms to international standards such as ASTM A681, AISI, and DIN 1.2379, ensuring consistent quality and performance.
Our production process includes strict chemical composition control, advanced heat treatment, and non-destructive testing to guarantee uniformity and reliability. All shipments come with mill test certificates (MTCs), chemical analysis reports, and optional third-party inspection for complete assurance.
Key Features & Advantages
Exceptional Wear Resistance: High chromium content provides outstanding hardness and abrasion resistance.
Dimensional Stability: Maintains precise size and shape after heat treatment.
Long Tool Life: Reduces replacement frequency compared with lower-grade tool steels.
Certified Quality: Fully compliant with ASTM, AISI, and DIN standards, with complete test reports.
Balanced Properties: Combines hardness with adequate toughness, preventing premature cracking.
Applications
D2 Tool Steel Bar is widely applied in:
Punches, dies, and cutting tools for stamping operations
Industrial knives and shear blades
Forming and trimming tools for sheet metal
Cold extrusion dies and thread rolling tools
Plastic and rubber molding components
