1.2080 is a high-carbon, high-chromium tool steel that conforms to the German standard DIN 17350. It is renowned for its exceptional wear resistance, high hardness, and good dimensional stability, making it suitable for applications requiring durability and precision under high-stress conditions. Due to its outstanding performance, many countries have developed equivalent steels to DIN 1.2080. Such as the American standard D3 (ASTM A681), the international standard X210Cr12 (ISO 4957), the Japanese standard SKD1 (JIS G4404), and the Chinese standard Cr12 (GB/T 1299).
1.2080 steel contains high levels of carbon (1.90-2.20%) and chromium (11.00-12.00%), which contribute to its excellent wear resistance and ability to retain hardness even under demanding conditions. The chromium content enhances its corrosion resistance and hardness, while the high carbon content ensures superior wear resistance and edge retention. These properties make 1.2080 an ideal choice for manufacturing cold work tools, such as blanking dies, forming dies, shear blades, and other components that require high wear resistance, long service life, and precise dimensional stability.

For 1.2080 steel, because we don’t use them in domestic market, so there is no stocks for that material, usually we use Cr8 steel instead of 1.2080 steel in China, Cr8 steel is with similar mechanical properties but lower cost.

2): Forging processing:
Put the 1.2080 ingot into the furnace and pre-heat to 700-800℃
Continue heating the ingot to initial temperature: 1050-1100℃
Forge the ingot, forging temperature should be not less than 850-900℃
Cooling in the sand or lime after forging

Heat 1.2080 steel to 820-850℃ in the furnace
Soak at this temperature in the furnace
Cooling in the furnace slowly
2): Quenching and tempering:
Preheat Temperature: 816℃
Heat 1.2080 steel to 960-980℃ in the salt bath furnace
Soak at this temperature in the furnace
Quench in oil
Temper steel at 170-190℃ in the furnace
Take out from furnace and cool in the air.
Above curve in figure is just a rough guide to the tempering behaviour of steels. When applying the curves for an estimation of the hardness which can be expected in quenched and tempered tools, it should be taken into account that the optimum heat-treatment conditions for the tools are not necessarily identical with those specified for the test pieces.
The heating time of test pieces in a salt batch shall be as give in below table:
Total heating time of test pieces in a salt bath
Nature of steel | Hardening Time min | Tempering Time min |
Cold or hot work steels | 25 +/- 1 | 60 |
High-speed steels | 3 | Minimum 2 periods of 60 each |
If the test pieces are not heated in a salt batch, the heating time must be extended accordingly, and the times for heating give above are not valid for thicker tools.
