Introduction
Super alloys are also called high performance alloys. They have the capacity to function under very high temperatures and severe mechanical stress, and also where high surface stability is required. They have good creep and oxidation resistance. Super alloys contain many elements in a variety of combinations so as to reach a desired result. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.
There are three types of super alloys, namely cobalt-base, nickel-base, and iron-base. All of these can be used at temperatures above 540°C (1000°F). Super alloy 30™ has low resistivity.
The following datasheet will provide more details about super alloy 30™.
