Abstract

Failures of stainless and heat-resistant austenitic CrNi steels frequently occur in practice due to incorrect material selection, improper processing or unforeseeable factors under operating conditions.

Selected examples will be used to illustrate various of these factors influencing the development of failure.

Kurzfassung

An nichtrostenden und hitzebeständigen austenitischen CrNi-Stählen treten in der Praxis häufig Schadensfälle durch falsche Werkstoffauswahl, unsachgemäße Verarbeitung oder unvorhersehbare Faktoren unter Betriebsbedingungen auf.

An ausgewählten Beispielen sollen verschiedene dieser Einflussfaktoren auf die Schadensentstehung gezeigt werden.
