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.
