M390 Stainless Steel for Knife Blades

Bohler M390 Stainless Steel

Manufacturer: Böhler Edelstahl

BÖHLER M390 MICROCLEAN grade is a corrosion resistant, martensitic chromium steel. Large percentages of small, finely dispersed Cr- and V-carbides in a matrix containing at least 12% chromium offer the following benefits:

  • highest corrosion resistance,
  • optimum wear resistance,
  • excellent polishability.

Bohler M390 was developed from the ground up as a knife steel and offers very high hardness in the 60+ HRC range and can be brought to a high polish. Several knife manufacturers have been using M390 including Kershaw and Benchmade who both use it quite extensively.
