Designations

• EN/DIN: 1.2080

• Steel name: X210Cr12

• AISI: D3

• ČSN/STN: 19 436

Chemical Composition (typical values)

• C: 2.00 – 2.35 %

• Cr: 11.00 – 13.00 %

• Mn: max. 0.40 %

• Si: max. 0.40 %

• P: max. 0.030 %

Properties

• Very high wear resistance (due to high hardness and chromium content).

• Good dimensional stability during hardening.

• Lower toughness (more brittle compared to other tool steels).

• Good compressive strength.

Heat Treatment

• Annealing (soft): 800 – 850 °C, slow cooling; hardness after annealing max. 230 HB.

• Hardening: 960 – 1000 °C, quenching in oil or air.

• Tempering: 150 – 300 °C depending on required hardness.

• Hardness after hardening: approx. 60 – 64 HRC.

Applications

• Cutting tools for sheet metal, punching and blanking dies.

• Rolls and tools for cold forming.

• Cutting and pressing tools.

• Moulds for plastics with abrasive fillers.
