Precipitation hardening stainless steels have been formulated so that they can be supplied in a solution treated condition, (in which they are machineable) and can be hardened, after fabrication, in a single low temperature "ageing" process.

Basic properties

  • Moderate to good corrosion resistance
  • Very high strength
  • Good weldability
  • Magnetic

Common uses

  • Shafts for pumps and valves
