UNS N07750 Alloy steel is mainly by γ [Ni3 (Al, Ti, Nb)] phase of nickel base superalloy aging strengthening, has good corrosion resistance and oxidation resistance at 980 degree, 800 degree with higher intensity, 540 degree with relaxation has good performance, but also has the forming and welding performance good. This alloy is mainly used in the manufacture of aero engine under 800 degree and requirements and high strength corrosion resistant ring parts, structural parts and bolts and other components, in 540 degree work with medium or low stress and resistance to planar spring relaxation and spiral spring. Also can be used in the manufacture of gas turbine blades. Can supply a variety of sheet, strip, bars, forgings, ring, wires and tubes.
