Common Trade Names: Incoloy 945; Alloy 945; Incoloy® alloy 945 (UNS N09945) is a high-strength, corrosion-resistant alloy designed for demanding applications in the oil and gas industry. The properties of this age hardenable nickel-iron-chromium alloy are enhanced by its contents of molybdenum, copper, niobium, titanium, and aluminum. The alloy’s nickel content results in resistance to chlorideinduced stress corrosion cracking. Nickel, in conjunction with the molybdenum and copper, also gives alloy 945 outstanding resistance to general corrosion in reducing media. Molybdenum also imparts resistance to localized attack (pitting and crevice corrosion). The alloy’s content of chromium provides resistance in oxidizing environments. Niobium, titanium and aluminum participate in the age hardening reaction that occurs during heat treatment. Their interaction forms gamma prime and gamma double prime precipitates, which strengthen the alloy. Available Product Forms: Round bar, forging stock, tube and wire ect. Specifications Incoloy® alloy 945 is designated as UNS N09945. The alloy is approved for use in oil and gas applications by NACE MR0175 / ISO 15156-3 up to NACE level VII and to level VI-450ºF.
