AMS HS 25

Profile

This page is mainly introduced the HS 25 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of HS 25,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
Haynes 25™ has an excellent temperature strength and oxidation resistance to 2000 ºF. Haynes 25™ is hot formable between 1900 ºF- 2300 ºF. Also known as Alloy L605, it is better to cold-work Haynes 25™ for bending, spinning and drawing the components.
