Super alloys comprise a number of elements in a variety of combinations to achieve the desired result. They have high creep and oxidation resistance. They are capable of functioning at very high temperatures and severe mechanical stress, and also where high surface stability is required. Solid-solution hardening, work hardening, and precipitation hardening are performed to increase their strength. There are three groups of alloys such as cobalt-based, nickel-based, and iron-based super alloys. All of these can be used at temperatures above 540°C (1000°F).

Sheet and Strip—Hot or cold rolled, annealed, and descaled unless annealing is performed in an atmosphere yielding a bright finish.

Plate—Hot rolled, annealed, and descaled.
