Description and uses

Alleima/Sandvik 10C28Mo2 is a martensitic stainless chromium steel developed for razor blade and knife applications
with high demands on corrosion resistance. The carefully chosen chemical composition in combination with a very fine microstructure also provides a high hardness, good edge retention, toughness and edges that are
easy to re-sharpen.
After heat treatment the grade is characterized by:
  • Very good corrosion resistance
  • High hardness which gives good wear resistance
  • Good toughness

Typical applications for Alleima/Sandvik 10C28Mo2 are:
  • kitchen knives and other tools where a dishwasher-safe material is required
  • professional butcher knives that need to be easily re-sharpened
  • outdoor knives
  • medical blades and razor blades, with high requirements on corrosion resistance and toughness.
