Incoloy 945X Chemical Composition
Incoloy 945X Material Properties Overview
As a leading supplier and manufacturer in China, Arialloy supplies cost effective incoloy 945X products.
Incoloy 945X (UNS N09946) is an age hardenable nickel iron chromium alloy strengthened by additions of molybdenum, copper, niobium, titanium and aluminum. Its composition combines strong corrosion resistance with very high mechanical strength.
Nickel improves resistance to chloride induced stress corrosion cracking, while molybdenum and copper enhance resistance in reducing media and molybdenum supports resistance to pitting and crevice corrosion. Chromium improves resistance to oxidizing environments. Niobium, titanium and aluminum promote finely distributed gamma prime and gamma double prime precipitates during age hardening, producing high yield strength, tensile strength, hardness and fatigue resistance while retaining useful ductility and impact toughness. In the solution annealed and aged condition, the alloy provides a minimum yield strength of about 140 ksi (965 MPa) and a minimum tensile strength of about 165 ksi (1138 MPa). It also retains a large proportion of its room temperature strength at moderately elevated temperatures and maintains good fracture toughness and cyclic performance.
Arialloy recommends incoloy 945X to buyers prioritizing very high strength, strong corrosion resistance and dependable mechanical stability across a broad temperature range.
Incoloy 945X Corrosion Resistance
Incoloy 945X provides strong resistance to chloride induced stress corrosion cracking, sulfide stress cracking, general corrosion, pitting and crevice corrosion.
Its high nickel content improves resistance to chloride attack, while nickel, molybdenum and copper strengthen performance in reducing media. Chromium supports resistance in oxidizing environments, and molybdenum improves localized corrosion resistance. The alloy also maintains resistance in environments containing hydrogen sulfide, carbon dioxide and concentrated chlorides.
Incoloy 945X Mechanical Properties
Incoloy 945X is precipitation hardened by finely distributed gamma prime and gamma double prime phases formed from niobium, titanium and aluminum.
In the solution annealed and aged condition, minimum yield strength is about 140 ksi (965 MPa), minimum tensile strength is about 165 ksi (1138 MPa), and elongation reaches 18%. Commercial bar data show yield strengths around 992 to 1025 MPa and tensile strengths around 1224 to 1275 MPa, together with good ductility, impact toughness and fatigue resistance. Cold worked and aged material can reach substantially higher strength and hardness.
Incoloy 945X Temperature Characteristics
Incoloy 945X retains a large proportion of its room temperature strength through moderately elevated temperatures. Rod testing shows average yield strength factors of about 0.91 at 149°C, 0.90 at 204°C and 0.88 at 232°C, while tubing data remain around 0.91 at 288°C. Fracture toughness also remains high through 232°C, and low cycle fatigue data demonstrate stable cyclic strength at this temperature.
Its age hardened microstructure supports strength retention, while chromium contributes oxidation resistance. Thermal conductivity rises progressively with temperature, while elastic modulus decreases in a predictable manner.
