FIELD: metallurgy, namely iron-nickel base alloys with high resistance against high temperature corrosion in melt alkali metal carbonates during long-time operation at temperature till 700°C , possibly used in fuel elements of electrochemical generators. ^ SUBSTANCE: iron-nickel base alloy contains chrome, nickel, aluminum, yttrium, carbon, titanium, silicon, manganese and iron at next relation of ingredients, mass %: carbon, no more than 0.2; manganese, 0.1 - 0.8; chrome, 28.0 - 32.0; nickel, 43.0 - 47.0; aluminum, 0.4 - 1.0; titanium, 0.1 - 0.5, yttrium, 0.03 - 0.05; iron, the balance. Such alloy provides low electric resistance no more than 250 megohm/cm2 for long time of its operation in melt carbonates of alkali metals. ^ EFFECT: improved corrosion resistance of alloy in melt carbonates of alkali metals, enhanced technological properties of material during metallurgical conversion and at making complex constructions with use of welding procedures. ^ 2 tbl, 1 ex |
