Nimonic 115

SHP

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.


Forming & Machining

Nimonic 115 has good ductility; forming is, therefore, superior although powerful equipment is needed as the alloy has greater strength when compared to conventional steels. Thorough cleaning after forming is required as lubricant residues can cause future embrittlement of the alloy. The alloy is machined using traditional machining methods and is work hardened during the machining process. High-speed processing requires a water-based coolant.


Weldability

An alloy filler for welding is required - this can either be an exact alloy match or a filler with high nickel, cobalt, molybdenum and chromium content. Suitable welding techniques include gas metal-arc welding, gas-tungsten ar welding, submerged-arc welding and shielded metal-arc welding.


In Motorsport

This superalloy offers a unique combination of high temperature and mechanical strength and is suitable for motorsport applications where high surface stability is required. Exhaust valves, fasteners, springs and engine components are good examples of where the alloy is suitable.


Product Availability

The alloy is available in round bar and plate.
