MIL MIL S 861

Profile

This page is mainly introduced the MIL S 861 chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of MIL S 861,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
MIL S 861 is a hardenable stainless steel designed for use at temperatures of up to 1200ºF (649ºC). MIL S 861 has good resistance to scaling and oxidation. Through heat treatment, high mechanical properties can be developed. MIL S 861 is used in applications such as compressors or steam turbines and also in aircraft parts, valves, high temperature bolting etc.
