Harden your stainless and exotic alloys with us!
This process is typically reserved for materials such as stainless steels, aluminum and nickel alloys including the aerospace exotics such as Inconel and Waspalloy, among others. Precipitation hardening and aging are similar processes, but they achieve different results for different materials. Both are generally performed in a highly uniform temperature controlled oven (i.e. +/- 10°F) to a set temperature for a set period of time at that temperature, before cooling in air to room temp.
Precipitation hardening for stainless steels is performed at or near the end of the manufacturing process, as it typically results in a significant increase in hardness by developing an alloy specific microstructure.
The aging process for nickel-based alloys can vary widely in temperature (1000 – 2080°F) and time and temperature are generally alloy specific. Aluminum aging is similar to a temper process for steels, where parts are heated in a highly uniform temperature controlled oven to a specific temperature and duration.
