Patentanspruch:Claim: Verwendung eines austenitischen Stahls mit in Gewichtsprozenten 0,25-1,0 Kohlenstoff (C), 10 - 20 Mangan (M n), 5 - 15 Chrom (Cr), höchstens 1 Silizium (Si), höchstens 2 Molybdän (Mo), höchstens 1 Vanadium (V), höchstens 0,5 Nickel (Ni), höchstens 0,5 Titan (Ti), höchstens 1.5 Niob (Nb) und Tantal (Ta) und einem Zusatz von 0,005 bis 1,5 Bor (B) als Werkstoff für Gegenstände, die kavitations- und erosionsbeständig sein müssen, beispielsweise für Armaturen und Bestandteile von Wasserkraftmaschinen. Use of an austenitic steel with a weight percentage of 0.25-1.0 carbon (C), 10 - 20 manganese (M n), 5 - 15 chromium (Cr), at most 1 Silicon (Si), max. 2 molybdenum (Mo), max. 1 vanadium (V), max. 0.5 nickel (Ni), max 0.5 titanium (Ti), at most 1.5 niobium (Nb) and tantalum (Ta) and an addition of 0.005 to 1.5 boron (B) as Material for objects that have to be resistant to cavitation and erosion, for example for Fittings and components for water power machines. Die Erfindung betrifft die Verwendung eines austenitischen Stahls mit in Gewichtsprozenten 0,25 — 1,0 Kohlenstoff (CV 10-20 Mangan (MnI 5-15 Chrom (Cr), höchstens 1 Silizium (Si), höchstens 2 Molybdän (Mo), höchstens 1 Vanadium (V), höchstens 0,5 Nickel (Ni), höchstens 03 Titan (Ti), höchstens 1,5 Niob (Nb) und Tantal (Ta) und einem Zusatz von 0,005 bis 1,5 Bor (B) als Werkstoff für Gegenstände, die kavitations- undThe invention relates to the use of an austenitic steel with a weight percentage of 0.25-1.0 Carbon (CV 10-20 Manganese (MnI 5-15 Chromium (Cr), max. 1 silicon (Si), max. 2 molybdenum (Mo), maximum 1 vanadium (V), maximum 0.5 nickel (Ni), maximum 03 titanium (Ti), maximum 1.5 niobium (Nb) and tantalum (Ta) and an addition of 0.005 to 1.5 boron (B) as a material for objects that are cavitation and Tafel APanel A erosionsbeständig sein müssen, beispielsweise Armaturen und Bestandteile von Wasserkraftmaschinen.Must be erosion-resistant, for example fittings and components of water power machines. Nichtrostende austenitische Stähle weisen im allgemeinen eine bessere Kavitations- und Erosionsbeständigkeit auf, als die klassischen Sorten von Konstruktionsstahl. Eine bekannte Stahlsorte (CH-PS 2 18 135) mil einem hohen Widerstand gegen Wasserschlag ist ein Chrom-Mangan-Stahl mit 0,1 — 1% Kohlenstoff (C), 10-25% Chrom (Cr) und 12-20% Mangan (Mn). Geeignete Zusätze, wie z. B. Wolfram (W), Molybdän (Mb), Titan (Ti) und Vanadium (V), verändern diese Eigenschaft nicht grundsätzl'ch.Austenitic stainless steels generally have better cavitation and erosion resistance than the classic grades of structural steel. 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 - 1% carbon (C), 10-25% chromium (Cr) and 12-20% Manganese (Mn). Suitable additives, such as. B. tungsten (W), molybdenum (Mb), titanium (Ti) and vanadium (V), do not fundamentally change this property. Die bisher erreichte Kavitations- und 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 cavitation and erosion resistance achieved so far is, however, with the steel types mentioned much smaller than with cobalt alloys. Their application, in turn, is difficult because of them Hot forming and its high brittleness are limited. Der erfindungsgemäß verwendete Stah'i 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 exceeds the previously known values for chromium / manganese with regard to its resistance to cavitation and erosion Steels in an unexpected way. In der nachstehenden Tafel »A« wird die Stahlzusammensetzung aufgeführt, und zwar des erfindungsgemäßen austenitischen Stahls, mit Bcr, einer bekannten Manganchromstahlscrte mit einer erhöhten Erosionsbeständigkeit, und einer Kobaltlegierung. The following table "A" shows the steel composition listed, namely of the austenitic steel according to the invention, with Bcr, a known one Manganese chrome steels with increased erosion resistance, and a cobalt alloy.
