In dem Patent 767 100 ist die Verwendung von molybdänfreien. Stählen mit weniger als 0,2%, vorzugsweise unter ο, 1 0Io Kohlenstoff, 0,2 bis 1,2% Titan sowie 1 bis 3,5°/» Chrom als Werkstoff für Gegenstände geschützt, die eine höhere Dauerstandfestigkeit besitzen sollen als Gegenstände aus entsprechenden. Titanstählen ohne den angegebenen Chromgehalt. Die durch den Zusatz von ChromIn the 767,100 patent is the use of molybdenum-free. Steels with less than 0.2%, preferably below ο, 1 0 Io carbon, 0.2 to 1.2% titanium and 1 to 3.5 ° / »chromium protected as a material for objects that should have a higher fatigue strength than Items from appropriate. Titanium steels without the specified chromium content. The by the addition of chrome

zu den. Titanstählen eintretende Steigerung der Dauerstandfestigkeit wird dabei auch dann noch erreicht, wenn die Stahllegierungen bis zu 2% Silizium und/oder bis zu 2°/o Aluminium enthalten. Es wurde nun gefunden, daß sich die Lehre des Hauptpatentes auch auf Stahlguß übertragen läßt. Gegenstand der Erfindung ist daher die Verwendung molybdänfreier Stähle gemäß Patent 767 100to the. Titanium steels will increase the fatigue strength even then achieved when the steel alloys contain up to 2% silicon and / or up to 2% aluminum. It has now been found that the teaching of the main patent can also be applied to cast steel. The invention therefore relates to the use of molybdenum-free steels according to patent 767,100
