Mechanical Properties
Tensile:≥830 MPa;Yield:≥415 MPa;Elong:≥30%;Hardness:≤240 HB
Equivalent Grades
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.
Applications
镍铬钼铌，耐蚀耐高温。,"Bar
Available Forms
Plate
Uses
Wire"
Heat Treatment
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.
Precautions
Solution treated 1050–1250 °C and aged (≈700–900 °C) to precipitate γ′/γ″ strengtheners; processed via vacuum induction + VAR/ESR for cleanliness.
