Incoloy 908 Chemical Composition
Incoloy 908 Material Properties Overview
As a manufacturer and supplier in China, Arialloy supplies incoloy 908 products for demanding material requirements.
Incoloy 908 (UNS N09908) is an age hardenable nickel and iron alloy that combines low thermal expansion with high strength and excellent cryogenic toughness. Its composition contains 47 to 51% nickel, 3.75 to 4.50% chromium, and additions of niobium, titanium, and aluminum. Iron forms the balance. The nickel and iron matrix provides its characteristic thermal expansion behavior, while precipitation strengthening increases resistance to mechanical deformation. Aluminum and titanium promote the formation of the gamma prime strengthening phase within the matrix. This metallurgical structure gives the alloy a useful combination of strength, ductility, and resistance to crack propagation.
The alloy retains substantial fracture toughness at cryogenic temperatures and resists fatigue crack growth during repeated loading. Its low thermal contraction closely matches that of niobium tin superconductors, reducing differential strain during cooling. Metallurgical stability during extended aging is another important feature, allowing the strengthening structure to develop without rapid transformation into less favorable phases.
Good ductility and weldability complement these properties and support fabrication into structural material. The combination of thermal compatibility and cryogenic mechanical performance makes incoloy 908 a specialist material for superconducting magnet sheathing and related cryogenic structures.
Incoloy 908 Corrosion Resistance
Incoloy 908 Mechanical Properties
Incoloy 908 combines high strength with substantial fracture toughness at cryogenic temperatures. At 4.2 K, solution annealed and aged material exhibits an average yield strength of approximately 1200 MPa and fracture toughness above 230 MPa√m. These properties provide strong resistance to plastic deformation and crack extension.
The alloy also resists fatigue crack propagation. Its fatigue crack growth rate at 4.2 K is approximately one third of that at room temperature, complementing its strength and toughness under repeated mechanical loading.
Incoloy 908 Temperature Characteristics
Incoloy 908 exhibits low thermal expansion and strong metallurgical stability during aging. Its thermal expansion coefficient is approximately 8.59 µm/(m·°C) at 93°C and 8.66 µm/(m·°C) at 260°C. The Curie temperature is approximately 282°C, above which its expansion behavior changes more rapidly.
Gamma prime precipitation provides thermal strengthening, and the alloy retains this phase without transformation to eta during exposures of up to 100 hours at 750°C. Together, these characteristics combine limited dimensional change at lower temperatures with resistance to overaging during thermal treatment.
