Description

Für Schweißdrähte zum Schweißen von nichtaustenitischem Eisen und Stahl oder deren Legierungen wurden schon verschiedene austenitische Stahllegierungen vorgeschlagen, u. a. auch austenitische Chromnickelmanganstähle. Bei diesen war aber der Gehalt an Chrom auf höchstens 5 o/o beschränkt/ da man befürchtete, daß ein höherer Chromgehalt die Sprödigkeit der Schweißstelle unzulässig vermehrt. Besonders bevorzugt wurden aber hierfür chromfreie Mangannickelstähle mit niedrigerem Kohlenstoffgehalt.Various austenitic steel alloys have already been proposed for welding wires for welding non-austenitic iron and steel or their alloys, including austenitic chromium-nickel-manganese steels. In these, however, the chromium content was limited to a maximum of 5 o / o / since it was feared that a higher chromium content would inadmissibly increase the brittleness of the weld. However, chromium-free manganese-nickel steels with a lower carbon content were particularly preferred for this purpose.

Es wurde nun gefunden, daß beim Schweißen von nichtaustenitischem Eisen und StahlIt has now been found that when welding non-austenitic iron and steel

'15 oder deren Legierungen gerade ein höherer Chromgehalt, der über 6 bis zu 30 0/0 beträgt, in austenitischen Chromnickelmanganstählen besonders günstig auf die Güteeigenschaften der Schweißnaht, insbesondere die Dehnung wirkt.15 or their alloys have a higher chromium content than 6 to 30 0/0, austenitic chromium-nickel-manganese steels have a particularly favorable effect on the quality properties the weld seam, in particular the elongation, acts.

Außerdem können diese Stähle noch Zusätze der Elemente Kobalt, Vanadin, Titan, Tantal o. dgl. in geringem Außmaße aufweisen. Beispiele für Schweißdrähte nach der Erfindung sind z.B. folgende:These steels can also contain additions of the elements cobalt, vanadium, titanium, Tantalum or the like to a small extent. Examples of welding wires according to the invention are, for example, the following:

I. 16,50/0 Chrom, γ o/o Mangan, ioo/0 Nickel, II. 9,0O7O Chrom, 6o/o Mangan, aio/o Nickel.I. 16,50 / 0 chromium, γ o / o manganese, ioo / 0 nickel, II. 9,0O 7 O chromium, 6o / o manganese, aio / o nickel.
