Abstract
The invention relates to an iron-, nickel-, chromium base alloy having an austenitic structure and good high temperature features, in-cluding a very high resistance against oxidization in oxidizing atmos-phere and against carburizing; in carburizing atmosphere at high tem-peratures, as well as high creep fracture resistance. The alloy has the following composition in weight-%: 0.01 - 0.08 C, 1.2. - 2.0 Si, from traces up to 2 Mn, 22 - 29 Cr, 32 - 38 Ni, 0.01 - 0.15 rare earth metals, 0.08 - 0.25 N, balance essentially only iron and unavoidable impurities and normally occurring accessory elements in normal amounts, said rare earth metals in combination with the said content of silicon im-proving the growth of a protecting; SiO2-layer on the mesal surface, when the metal surface is subjected to high temperatures in oxidiz-ing atmosphere, which counteracts the transportation of metal ions, in the first place chromium, out of the alloy, so that scaling is mini-mized.
