DIN 1.2080

Alloy tool steel with high wear resistance

DIN 1.2080 is an alloyed tool steel with a chromium content of approximately 12%. It has a very high hardness after hardening and excellent wear resistance, but has a lower toughness, making it more brittle than other tool steels. It is used where resistance to wear and abrasive stress is crucial.


Alternative designation : X210Cr12, ČSN 19436

Type : High-alloy tool steel (for cold work)

Heat treatment:

  • Preheat: 650–800 °C

  • Quenching: 950–1050 °C (air or oil)

  • Tempering: 150–200 °C (target hardness up to 64 HRC)
