Product description

With proper heat treatment (hardening), 1.4034 achieves a hardness of 56 to 60 HRC, giving it very good edge retention. It is therefore not comparable to industrial/production knives, where it is only hardened to about 52-55 HRC and its potential is not nearly fully utilized.

1.4034 steel / AISI 420HC or Böhler N540 (x46cr13) is a hardenable chromium steel.
