Tool Die Steel – High Wear Resistance for Cold Work Applications

Tool Die Steel is a high-performance cold work tool steel designed for demanding industrial applications requiring excellent wear resistance, dimensional stability, and high hardness. Manufactured using advanced spray forming powder metallurgy technology, this material delivers a more uniform microstructure compared to conventional casting methods.

Also known as:

1. GB: Cr12Mo1V1
2. AISI: D2
3. DIN: 1.2379
4. JIS: SKD11

This steel grade is widely used in stamping molds, shear knives, thread rolling dies, and precision wear-resistant tooling.

Why Choose Tool Die Steel?

Compared with traditional D2 steel, spray forming powder metallurgy processing offers:

1️⃣ Superior Microstructure Uniformity

Spray forming reduces carbide segregation and ensures fine, evenly distributed carbides, improving mechanical consistency and tool life.

2️⃣ Enhanced Wear Resistance

With high chromium and carbon content, Tool Die Steel provides outstanding abrasion resistance, making it ideal for long production runs.

3️⃣ High Hardness After Heat Treatment

After proper hardening and tempering, hardness can reach HRC 57–62, ensuring excellent cutting and forming performance.

4️⃣ Improved Dimensional Stability

Suitable for precision dies where tight tolerances must be maintained.

Heat Treatment Parameters

• Annealed Hardness: HB 255
• Hardening Temperature: 1010–1030°C
• Tempering Temperature: 180–500°C
• Tempered Hardness: HRC 57–62

These properties make Tool Die Steel highly suitable for cold work environments.

Typical Applications

Tool Die Steel is widely used for:

1. Wear-resistant press tools
2. Stamping molds
3. Shear blades and cutting knives
4. Thread rolling dies
5. Guide plates
6. Porcelain mold components

Its excellent wear resistance and compressive strength make it ideal for high-load, repetitive production operations.
