Use of iron-chromium-aluminum alloys with specified composition in 0.020 -0.300 mm thick foils for heating elements is new

摘要

Use of iron-chromium-aluminum alloys in 0.020 -0.300 mm thick foils for heating elements is new, where the alloys have the composition (wt%): aluminum 4.5 - 6.5; chromium 16 -14; silicon 0.05 - 0.7; manganese 0.001 - 0.5; yttrium 0.02 - 0.1; zirconium 0.02 - 0.1; hafnium 0.02 - 0.1; carbon 0.003 - 0.20; N 0.03 max; S 0.01 max; S 0.01 max; Cu 0.5 max, the remainder being iron.
