Abstract
Steels on Fe-Cr-Mn base various structural classes: steel 30Cr2Mn6Si2V ? martensite, steel 30Cr8Mn6Si2V ? austenite, 20Cr14Mn7; surfacing 20Cr12Mn9SiTiNV ? austenite-martensite, 08Cr22Mn6SiV ? ferrite-austenite was investigated after carburizing, steel 09Cr17Mn9SiNi after carbonitriding and quenching from different temperatures.Used Following methods of investigation: optical metallography, chemical and spectral analysis, hardness and micro-hardness measurement, impact test, wear test of dry friction (metal to metal)
