Lochkorrosion an passiven Legierungssystemen der Elemente Eisen, Chrom und Nickel

Abstract: Die Lochkorrosion an nichtrostenden Stählen und Nickellegierungen stellt ein ernsthaftes Problem für die Praxis dar, insbesondere für die chemische Industrie, weil durch die Häufigkeit des Auftretens und die meist hohe Wachstumsgeschwindigkeit der entstehenden Löcher eine erhebliche Beschränkung der Lebensdauer von Bauteilen und Produktionsanlagen und u. U. auch eine Gefährdung der Umwelt eintreten kann. Von besonderem Nachteil ist hierbei die beinahe uneingeschränkte Verbreitung der lochfraßauslösenden Chlori… Show more

“…It increases with the annealing temperature and rate of cooling. It should be noted that there is a risk of "475°C embrittlement" (hardness increase, loss of toughness, and loss of chemical resistance through separation into phases of high iron and chromium content [54] and σ-phase formation). Furthermore, in comparison with purely austenitic steels, these steels are less sensitive to stress corrosion cracking.…”

“…It increases with the annealing temperature and rate of cooling. Attention is drawn to the risk of 475 C embrittlement (hardness increase, loss of toughness, and loss of chemical resistance through separation into phases of high iron and chromium content [52] and s-phase formation), as well as to the fact that, in comparison with purely austenitic steels, these steels are less sensitive to stress corrosion cracking. Their applications include pump manufacture.…”
