Super alloys are also referred to as high performance alloys. They contain many elements in a variety of combinations so as to achieve the desired result. These alloys can function under very high temperatures and severe mechanical stress, and also where high surface stability is required. They have good creep and oxidation resistance. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

The following datasheet will provide more details about HASTELLOY(r) B-3.
