NIMONIC 115 is a nickel chromium cobalt superalloy designed for heavily loaded turbine blades. Aluminum and titanium develop precipitation strengthening, while molybdenum contributes solid-solution strength. Its principal advantage is resistance to creep at very high temperatures. Product selection should account for forging practice, final aging and the operating stress, because these factors strongly influence blade life.
