Abstract (en)
[origin: WO2022090781A1] The invention relates to an alloy having the following composition by weight: 16.5% ≤ Cr ≤ 25.0%; 11.0% ≤ Mo ≤ 18.0%; 2.0% ≤ W ≤ 7.0%; Fe ≤ 1.0%; Mo+W ≤ - 0.5 x (Cr+Fe) + 30%; Mo+W ≥ - 0.5 x (Cr+Fe) + 25%; Ti+Ta ≤ 0.80%; 0.01% ≤ Si ≤ 0.75%; 0.01% ≤ Al ≤ 0.35%; 0.01% ≤ Mn ≤ 0.35%; Ca ≤ 0.005%; Mg ≤ 0.005%; Nb ≤ 0.01%; 0.001% ≤ C ≤ 0.05%; 0.001% ≤ N ≤ 0.05%; S ≤ 0.003%; P ≤ 0.005%; optionally 0.0010% ≤ rare earths ≤ 0.015%, the silicon content being less than or equal to 0.25% in the presence of rare earths in an amount between 0.0010% and 0.015%, the balance being nickel and inevitable impurities resulting from the processing, the nickel content being greater than or equal to 54%.
