Nimonic® 115
(UNS N06115)

Our nickel-chromium-based alloy introduces molybdenum, titanium and aluminium for additional strength.

Nimonic® 115 is a precipitation-hardenable alloy available for supply in bar form and extruded sections.

Elevated Temperature Service:

The material is a creep-resisting alloy, initially developed for high-temperature service operation up to 1010°C. The product's original intended application was producing gas turbine blades, offering superior oxidation resistance and high-temperature strength. Heat treatment of the product is by solution treatment and then ageing. The density of the product is 7.85 g/cc.

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 standard steels. Thorough cleaning after forming is required as lubricant residues can cause future embrittlement of the alloy. The alloy is machined using conventional machining methods and is work hardened during the machining process. Processing at high speeds requires a water-based coolant.

In Motorsport:

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

Welding:

We recommend using an alloy filler for welding - 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 arc welding, submerged-arc welding and shielded metal-arc welding.
