Haynes R-41 alloys have good creep and oxidation resistance, and are formed in different shapes. They are classified into three types such as cobalt-based, nickel-based, and iron-based super alloys. They have the ability to function at very high temperatures and under mechanical stress.
They can be strengthened by performing solid-solution hardening, work hardening, and precipitation hardening. The cobalt-based and nickel-based super alloys can be in the form of wrought or cast based on their application or composition.
Haynes(r) R-41 is a wrought nickel base high temperature and strength alloy. Double aging and solution heat treating are performed at low temperatures in order to increase its strength.
