How does UNS S66286 perform at high temperatures?

UNS S66286 has better high-temperature strength than austenitic stainless steel below 700°C.

UNS S66286, also known as Inconel 660 or Hastelloy X alloy, is a precipitation-hardening heat-resistant stainless steel. By increasing the nickel (Ni) content and adding titanium (Ti), aluminum (Al) and other alloying elements, after age hardening treatment, the γ' phase (fcc_Ni3 (Al, Ti)) will precipitate. The precipitation of this phase shows Significantly improves the high temperature strength of the material. Specifically, UNS S66286 features include:

High temperature performance: In the temperature range below 700°C, UNS S66286 exhibits superior high temperature strength than austenitic stainless steel such as SUS 304.
Age hardening treatment: Through age hardening treatment, the high-temperature strength of UNS S66286 is significantly improved, which is due to the precipitation of γ' phase in its microstructure.
Application areas: Due to its excellent high temperature performance, UNS S66286 is widely used in aerospace, petrochemical, energy and other high temperature and high pressure environments.
In summary, UNS S66286 is a material that performs well in high temperature environments, especially in the range below 700°C. Its strength and heat resistance make it an ideal choice for many high temperature applications.
