Age Hardening

Age hardening is a heat treatment technique used to increase the hardness of an alloy by a relatively low-temperature heat treatment that causes precipitation of components or phases of the alloy from the supersaturated solid solution. Age hardening is also known as precipitation hardening.
Unlike traditional hardening at temperatures that exceed 1500℉, most aging materials are processed below 1200℉ with no quenching required. This results in much less distortion versus traditional heat treating.

Examples of Aging (Precipitation)

Hardening materials are:

  • 17-4 SS
  • 13-8 SS
  • 15-5 SS
  • Unimar 300K
