DIN1.2080 tool steel

DIN 1.2080(X210Cr12) Cold Worked Tool Steel

DIN 1.2080 (equivalent to AISI D3 and JIS SKD1) is a high-carbon, high-chromium alloy tool steel (1.90-2.35% C, 12% Cr) renowned for exceptional wear resistance and compressive strength. Its matrix, enriched with hard carbides, effectively resists abrasive and adhesive wear, making it ideal for high-stress, long-life precision tooling applications. After oil quenching or vacuum gas quenching (for small sections), it achieves a hardness of 58-64 HRC with excellent dimensional stability and durability. However, brittleness during hardening requires careful process control. Compared to D2 steel, DIN 1.2080 offers superior wear resistance but slightly lower grindability, making it the preferred choice for shear blades, stamping dies, and wear-resistant plastic molds.

4.Heat Treatment Processes

• Heat Treatment

DIN1.2080 tool steel requires hardening and tempering to achieve maximum properties. For maximum accuracy, the parts of D3 tool steel should be stress relieved after roughing operations. Stress should be relieved at 648°C (1200°F) for one hour and cooled slowly.

• Annealing

DIN1.2080 tool steels uniformly to 850-870°C, soak thoroughly, then slow furnace cool at a rate of not more than 25°C per hour to 650°C. The parts may then be air cooled. This should result in a maximum hardness of brinell 248.

• Tempering

DIN1.2080 cold work steel should be cooled to room temperature and should be tempered immediately. The parts should be placed in the tempering furnace and increased slowly to the desired tempering temperature. Tempering for 1 hour per inch of thickness is required.

• Hardening

DIN1.2080 tool steel is extremely sensitive to overheating during hardening – do not overheat.

Pre heat slowly to 800-850°C, the raise rapidly to 950-970°C and soak until completely equalised. Quench in oil.

5.Forging & Machining Guidelines

• Forging Temperature: Preheat to 900-950°C; final forging ≥900°C. Use light initial blows to prevent cracking.

• Grinding: Use CBN or diamond wheels with low-speed, fine-grit operations due to high carbide content.

6.Typical Applications

• High-Wear Tools: Shear blades, blanking dies, stone-cutting tools.

• Precision Forming: Deep drawing dies, pressure pads, high-wear plastic molds.

• Sheet Metal Processing: Thin-sheet punches, paper/plastic cutting knives, profile rolls.
