Physical Properties


Super alloys or high performance alloys consist of many elements in a variety of combinations to achieve a desired result. They have good creep and oxidation resistance, and can function where high surface stability is required. They can be also used at very high temperatures and severe mechanical stress. Solid-solution hardening, work hardening, and precipitation hardening are performed for strengthening these alloys. Cobalt-based, nickel-based, and iron-based alloys are three types of super alloys.

Super alloy Mar M 247™ is a nickel-based super alloy. The datasheet given below provides an overview of Mar M 247™.
