Steel 1.2379 - CH16V

1.2379 - CH16V steel:
dimensional stability and wear resistance.

What?

1.2379 – CH16V steel is a high chrome alloy ledeburitic steel with Mo and V additives. These additives increase cutting stability, hardenability and the through-hardenability. Dimensional stability is good. The ledeburitic structure ensures high wear resistance. CH16V can be nitrided after special heat treatment.
