Martensitic stainless steels were the first stainless steels commercially developed (as cutlery) and have relatively high carbon content (0.1 - 1.2%) compared to other stainless steels. They are plain chromium steels containing between 12 and 18% chromium.

Basic properties

  • moderate corrosion resistance
  • can be hardened by heat treatment and therefore high strength and hardness levels can be achieved
  • poor weldability
  • magnetic

Common uses

  • knife blades
  • surgical instruments
  • shafts
  • spindles
  • pins
