Description
Verfahren zur Herstellung von Gegenständen mit zähem Kern und hochverschleißfesten Arbeitsflächen Die Erfindung betrifft ein Verfahren zur Erhöhung der Verschleißfestigkeit von Gegenständen aus einer austenitischen - Manganstahllegierung. Es ist bereits, vorgeschlagen worden, austenitische Manganstähle mit Zusätzen von Chrom, Wolfram, Molyb.dänoder Vanadin zu verwenden, wobei die Zusätze einzeln ioder gemeinsam benutzt werden, @um die Verschleißfestigkeit ödes Stahles zu erhöhen. Es ist auch schon der Vorschlag gemacht worden, den handelsüblichen Manganhartstahl in bekannter Weise , aufzukohlen, um ,dem unter der Kohlungszone liegenden Baustoff Zeit .zu lassen, sich während der im Betrieb auftretenden Kaltverformnung zu härten.Process for the production of objects with a tough core and highly wear-resistant Work surfaces The invention relates to a method for increasing wear resistance of objects made of an austenitic - manganese steel alloy. It is already, it has been proposed to use austenitic manganese steels with additions of chromium, tungsten, To use molybdenum or vanadium, the additives being used individually or together to increase the wear resistance of barren steel. It's also beautiful the proposal was made to use the standard manganese steel in a known manner to carburize in order to give the building material lying under the carbonization zone time. to harden during the cold deformation that occurs during operation.
Das die Erfindung bildende Verfahren. besteht nun darin, @daß Gegenstände aus einer austenitischen Manganstahllegierung, die Zusätze rann ¢ bis 18 % Chrom, Wolfram, Molybdän oder Vanadin, einzeln .oder zusammen, enthält, in einer .über das übliche Maß weit hinausragenden Tiefe und Höhe zementiert und .bei einer Temperatur von goo bis i i oo° C abgeschreckt werden. Die auf diese Weise hergestellten Gegenstände besitzen einerseits seinen zähen Kern und andererseits tiefe, hochverschleißfeste Arbeitsflächen. Bei der Prüfung seiner nach dem neuen Verfahren behandelten Legierung hat sich gezeigt, daß bei einer spezifischen Belastung von 50 kg/mm2 eine 16fache Verschleißfestigkeit gegenüber den bisher üblichen Werten. !erreicht wird. Es ist damit zu rechnen, daß die Verschleißfestigkeit bei Anwendung eines geringeren spezifischen Flächendruckes noch erheblich höhere Werte ergibt.The process of forming the invention. now is to @ that articles of an austenitic manganese steel alloy additives ran ¢ to 1 8% chromium, tungsten, molybdenum or vanadium singly .or together containing cemented in a .about the usual level far projecting depth and height. be quenched at a temperature of goo to ii oo ° C. The objects produced in this way have, on the one hand, a tough core and, on the other hand, deep, highly wear-resistant work surfaces. When testing his alloy treated according to the new method, it has been shown that at a specific load of 50 kg / mm 2 it is 16 times the wear resistance compared to the values customary up to now. ! is achieved. It is to be expected that the wear resistance results in considerably higher values when a lower specific surface pressure is used.
