Da Incoloy-Legierungen im Vergleich zu Hastelloy einen hohen Eisengehalt aufweisen, ist ihr WAK besser mit Kohlenstoffstahlm\u00e4nteln kompatibel, was das Risiko eines Versagens der Rohr-Boden-Verbindung w\u00e4hrend der thermischen Zyklen verringert.<\/p>\n<p data-path-to-node=\"13\">Furthermore, in environments containing sulfur (common in refinery &#8220;bottom-of-the-barrel&#8221; processing), the chromium content in these alloys facilitates the formation of a protective Cr-oxide scale.
