1.2436 (X210CrW12) tool steel is a cold work steel with a ledeburitic structure and 12% chromium content. It has very high wear resistance.
It is a tungsten-added version of 1.2080 steel. Compared to 1.2080, 1.2436 steel has better hardenability towards the core and higher toughness. However, it lacks secondary hardening capability.
The wear resistance of 1.2436 (X210CrW12) steel is higher than that of 1.2379, but its toughness is lower.
