Abstract:
Creep-proof and corrosion-resistant nickel-based alloy comprising, in wt-%:0.0015 to 0.60 carbon (C); 0.20 to 0.90 nitrogen (N); 22.0 to 32.0 chromium (Cr); 5.0 to 20.0 elements of the groups 4, 5, and 6 of the periodic table, except Cr; 0.03 to 3.0 aluminum (Al); 0.4 to 3.0 silicon (Si); maximum of 0.014 phosphorus (P); maximum of 0.004 sulfur (S); up to 0.60 manganese (Mn); minimum of 51 of nickel (Ni) or a combination of nickel (Ni) and cobalt (Co); and melting-related contaminants, and the alloy including at least one of nitrides or carbides in intercrystalline regions to substantially prevent intercrystalline sliding due to stable deposits in the intercrystalline regions.
