Sanicro70

High-Temp Steel

Sanicro70

Specialty steel grade. ; equiv Sanicro 70 / UNS N06600). Nominal values—confirm mill certificate.

Chemical Composition (%)

NI72
CR14
FE6

Mechanical Properties

Tensile:≥550 MPa;Yield:≥240 MPa;Elong:≥30%

Applications

镍铬耐热抗氧化。,Tube

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
