Precipitation Hardening Grades

Precipitation hardening stainless steel, like the martensitic types, can be strengthened and hardened by heat treatment. Both martensitic or austenitic precipitation hardening structures can be produced. These stainless steels combine high strength and hardness with corrosion resistance which is superior to that of the martensitic chromium stainless steels. All precipitation hardening stainless steel contains a relatively high chromium content. Most applications of precipitation hardening stainless steel plate are for corrosion resistance or oxidation resistance and retention of strength at elevated temperatures.

Please contact us directly with technical questions.

Martensitic PH steels are used in aerospace, chemical and petrochemical, and food processing applications.

Applications include:

  • Gears
  •  Valves and other engine components
  •  High strength shafts
  •  Turbine blades
  •  Moulding dies
  •  Nuclear waste casks

Precipitation hardening stainless steels have many advantages, due to their chromium and nickel content, such as :

  • Ability to gain high strength through heat treatment
  • Corrosion resistance
  • High tensile strengths
  • Can be supplied in a “solution treated” condition, which is readily machinable
  • Can be age-hardening, so material undergoes no distortion
