About Alloy
Nimonic 115 is a precipitation-hardenable alloy which is available for supply in bar form and extruded sections. The material is known as a creep-resisting alloy and with initial development for high-temperature service operation up to 1010°C.
Offering superior oxidation resistance and high-temperature strength, the original intended application for this product was in the production of gas turbine blades. Heat treatment of the product is by solution treatment and then ageing.
