Abstract

Es wird ein hochlegierter Eisen-Kohlenstoff-­ Gußwerkstoff mit einem austenitischem Grundgefüge, dessen Kohlenstoff Überwiegend aus Graphit vorliegt, vor­ geschlagen, bei dem der Graphit zum überwiegenden Teil als vermiculare Graphitausscheidung ausgebildet ist und der bevorzugt einen Restmagnesiumgehalt von 0,01 bis 0,04 Gew.-% aufweist. Ein Verfahren zur Herstellung des erfin­ dungsgemäßen Werkstoffes zeichnet sich dadurch aus, daß der Basiseisen-schmelze ein Behandlungszusatz aus Rein­ magnesium zugegeben wird, wobei sogar schwefelreiche Basiseisenschmelzen verarbeitet werden können. It becomes a high-alloyed iron-carbon Cast material with an austenitic structure, whose carbon is predominantly from graphite struck, in which the graphite as vermicular graphite precipitation is formed and the preferably a residual magnesium content of 0.01 to 0.04 % By weight. A method of making the inventions Material according to the invention is characterized in that the base iron melt is a treatment additive made of pure magnesium is added, even sulfur-rich Base iron melts can be processed.
