Incoloy 907 Chemical Composition
Incoloy 907 Material Properties Overview
As a manufacturer and supplier in China, Arialloy supplies incoloy 907 products for industrial procurement.
Incoloy 907 (UNS N19907) is a precipitation hardening alloy containing iron, nickel and cobalt, with additions of niobium and titanium. Its principal characteristics are low thermal expansion, high strength after aging and improved notch rupture performance compared with incoloy 903. The balance of nickel and cobalt gives the alloy its characteristic expansion behavior. Niobium and titanium contribute to precipitation strengthening, while the low aluminum content improves the combination of strength, ductility and resistance to fracture at areas of concentrated stress.
Solution treatment changes the distribution of Laves phase and the size of the matrix grains. Dissolution of these phases and grain growth reduce obstacles to dislocation movement, lowering strength while increasing elongation. Subsequent aging establishes the strengthened material condition. Different aging schedules produce distinct combinations of tensile strength and rupture resistance through changes in precipitate formation and distribution. The resulting microstructure directly influences deformation behavior. The solution treated condition facilitates subsequent forming operations. Its low expansion and relatively stable elastic modulus contribute to dimensional stability during heating and cooling.
Arialloy recommends incoloy 907 for customers prioritizing low thermal expansion, high strength, thermal stability, fatigue resistance and hydrogen compatibility.
Incoloy 907 Corrosion Resistance
Incoloy 907 has moderate overall corrosion resistance, with its strongest environmental advantage being resistance to embrittlement in high pressure hydrogen. The alloy contains essentially no chromium so that its low thermal expansion can be maintained, but this chemistry gives it lower oxidation resistance than chromium bearing nickel alloys. Nickel contributes to general corrosion resistance, while the absence of chromium limits protection in strongly oxidizing and aggressive chemical media.
Incoloy 907 Mechanical Properties
After aging for maximum tensile properties, incoloy 907 flat bar exhibits room temperature tensile strength of approximately 1341 MPa, 0.2% offset yield strength of 1120 MPa and elongation of 15%. At 649°C, corresponding values are approximately 1043 MPa, 870 MPa and 10.2%.
Aging for improved rupture performance produces room temperature tensile strength of approximately 1210 MPa, yield strength of 886 MPa and elongation of 16%. This treatment favors notch rupture strength through changes in precipitate distribution.
Incoloy 907 Temperature Characteristics
Incoloy 907 exhibits a thermal expansion coefficient of approximately 7.2 to 8.1 µm/m/°C at temperatures up to about 430°C. Its elastic modulus remains relatively stable from cryogenic temperatures to approximately 650°C. The Curie temperature lies between approximately 400°C and 455°C, with thermal expansion increasing beyond this transition region.
Low expansion and stable stiffness contribute to resistance to thermal fatigue and thermal shock. Expansion behavior remains reproducible after both sustained thermal exposure and repeated heating and cooling. The melting range is approximately 1335°C to 1400°C.
