Die erfindungsgemäßen Stähle eignen sich besonders für alle Anwendungsζwecke, wo entlang aller drei Achsen Spannungen und Beanspruchungen auftreten. Sie eignen sich auch für Anwendungszwecke unter korrodierenden Bedingungen selbst unter starker Beanspruchung; die Spannungskorrosion in stark salzhaltiger Umgebung ist gegenüber den bekannteren Stählen überraschend verbessert. The steels according to the invention are particularly suitable for all application purposes, where along all three axes Tensions and stresses occur. They are also suitable for uses under corrosive Conditions even under heavy use; there is stress corrosion in a highly saline environment surprisingly improved compared to the better-known steels.
