Precipitation Hardened Stainless Steels

Precipitation hardened stainless steels offer:

  • Excellent resistance to stress corrosion and cracking in substances containing chloride (e.g. seawater)
  • High resistance to sulfuric acid and nitric acids

Precipitation/age-hardened stainless steels are commonly used where high strength and improved corrosion resistance are required. For example:

  • Highly stressed machined castings in the aircraft and food processing industries
  • Pumps
  • Valves
  • Stressed components in the marine, chemical, textile and paper industries
