1.2080 is German cold die steel, metal, stamping template.It has the characteristics of high hardenability, high hardness, high abrasion resistance, quenching deformation correction and good toughness.
DIN 1.2080 / X210Cr12 Steel is a high Carbon and high Chromium cold work tool steel. The 1.2080 steel has good hardenability and wear resistance. But due to the carbon content of X210Cr12 steel is high,which makes this material hard and brittle. So din 1.2080 can not afford a bigger punch load and has low impact toughness.
Songshun Mould Steel supply high carbon high chromium 1.2080 flats cut from block and a limited range in round bar diameters. This tool steel specification is noted for its resistance to abrasion. It offers excellent dimensional stability in hardening. After heat treatment the tool steel is hard, durable, dense, and is immune from sinking in use. It offers a measure of corrosion resistance when polished. In general, the applications of 1.2080 tool steel resemble those of 1.2379 but it should be remembered that 1.2080 has better wear resistance of the two steels and is preferred for such items as shear blades. Owing to its higher wear resistance, 1.2080 tool steel is slightly more difficult to grind than 1.2379.

● Thermal Properties
12 x 10-6/ºC
6. Heat Treatment of DIN 1.2080 steel
● Heat Treatment
D3 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.
Heat D3 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.
The D3 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.
D3 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 equalized. Quench in oil.
7. Applications of DIN 1.2080 steel
DIN 1.2080 steel has high strength, good hardenability and wear resistance. 1.2080 is suitable for applications such as complex blanking and forming tools for long runs and for hard and abrasive materials.
