Mechanical Properties

Tensile:≥1275 MPa;Yield:≥1035 MPa;Elong:≥12%

Applications

沉淀硬化镍基，航空主力。,Forging

Available Forms

Nickel/cobalt-base superalloy retaining high strength, creep and corrosion resistance at extreme temperature. Used in gas-turbine blades, aero-engine hot sections, combustors and advanced energy systems.

Uses

Solution treated 1050–1250 °C and aged (≈700–900 °C) to precipitate γ′/γ″ strengtheners; processed via vacuum induction + VAR/ESR for cleanliness.

Heat Treatment

Machining is difficult — use ceramic/PCBN tools, generous coolant and rigid setups. Keep clean (vacuum/inert melting) to avoid inclusions; avoid contamination by low-melting elements.

Precautions
