| With proper heat treatment (hardening), 1.4034 achieves a hardness of 57 to 60 HRC, giving it very good wear resistance. Therefore, it cannot be compared to industrial/production knives, where it is only hardened to about 55 HRC and its potential is not nearly fully utilized. |
1.4034 steel / AISI 420HC or Böhler N540 (x46cr13) is a hardenable chromium steel.
