Nichtrostende austenitische Stähle weisen im allgemeinen eine bessere Kavitations-Erosionsbeständigkeit auf als die klassischen Sorten von Konstruktionsstahl.Austenitic stainless steels generally have has better cavitation erosion resistance than the classic grades of structural steel.

Eine bekannte Stahlsorte (CH-PS 2 18 135) mit einem hohen Widerstand gegen Wasserschlag ist ein Chrom-Mangan-Stahl mit 0,1 bis 1% Kohlenstoff, 10 bis 25% Chrom und 12 bis 20% Mangan. Geeignete Zusätze, wie z. B. Wolfram, Molybdän, Titan und Vanadium verändem diese Eigenschaft nicht grundsätzlich.A well-known type of steel (CH-PS 2 18 135) with a high resistance to water hammer is a chromium-manganese steel with 0.1 to 1% carbon, 10 to 25% chromium and 12 to 20% manganese. Suitable additives such as z. B. change tungsten, molybdenum, titanium and vanadium not fundamentally this property.

Die bisher erreichte Kavitations-Erosionsbeständigkeit ist jedoch bei den genannten Stahlsorten wesentlich kleiner als bei Kobaltlegierungen. Deren Anwendung wiederum ist wegen ihrer schwierigen Warmumformung und ihrer hohen Sprödigkeit begrenzt. The previously achieved cavitation erosion resistance is, however, much smaller in the case of the steel types mentioned than in the case of cobalt alloys. Whose In turn, application is limited because of their difficult hot forming and high brittleness.

Der erfindungsgemäfJ verwendete Stah' übertrifft hinsichtlich seiner Kavitations- und Erosionsbeständigkeit die bislang bekannten Werte bei Chrom/Mangan Stählen in einer unerwarteten Weise.The steel used according to the invention is superior the previously known values for chromium / manganese with regard to its resistance to cavitation and erosion Steels in an unexpected way.
