Super alloys or high performance alloys include iron-based, cobalt-based and nickel-based alloys. These alloys contain good oxidation and creep resistance and are available in different shapes.
Super alloys can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods. These alloys can function under high mechanical stress and high temperatures and also in places that require high surface stability.
Duranickel alloy 301 is an age-hardenable alloy and has greater hardness and strength in comparison with Nickel 200 alloy.
