摘要

Analiza cheltuielilor de fabricatie ale pieselor finite din FgnB a demonstrat posibilitatea reducerii pretului la mai mult de jumatate, fa comparatie cu piesele executate din oteluri de imbunatatire laminate. Dupa ealirea izoterma a fontelor cu grafit nodular la temperaturi cuprinse intre 300...400 deg C cu un timp de mentinere de 2...2.5 ore, rezulta cafcateristici mecanice comparabile (unele superioare), fata de cele ale otelurilor de imbunatatire.
