Corrosion resistant steels - Martensitic precipitation hardening (PH ) steels

Steels with 10 to 17% Chromium, low Carbon and Nickel content result in a microstructure of tough martensite and achieve strengths of up to 1700 MPa by alloying with Copper or Aluminium with simple low distortion and hardening treatment. Preferred areas of application under corrosive environments are aerospace, the oil and gas industry and measurement and control technology.
