Precipitation hardening is used in a wide variety of materials to increase the yield strength. It involves 3 steps: heat to a high temperature, quench, and age. With regard to steel, precipitation hardening is mostly carried out on stainless steels and superalloys. With the proper alloying elements and related precipitates, it is possible to limit the movement of dislocations in the lattice and hence increase hardness.


  • Harder and stronger material
  • Adds strength to a class of stainless steels
  • Wear resistance
  • Low distortion
