OXIDATION RESISTANT FE-NI-CR ALLOY BY RESTRICTING MN CONTENT

摘要

The oxidation resistance at elevated temperatures, e.g. 982 DEG C and above, of iron-nickel-chromium alloys of specified composition is improved by limiting the manganese content to a maximum value of 0,6%. The preferred alloy consists of: Ni 20 to 45 % Cr 15 to 25 % C up to 0,3 % N up to 0,3 % A1 up to 1 % Ti up to 1 % Cu up to 2 % Si up to 1,5 % Mn up to 0,6 % Fe balance. 1
