Conclusions
-
1.
Under certain conditions sulfur is a suitable alloying element for cast iron that increases the strength and ductility due to the fact that it slows down primary graphitization during solidification of the ingot and imparts a compact form to the graphite inclusions after graphitization annealing or self-annealing.
-
2.
By a combination of simple technological measures it is possible to obtain castings which are cheaper than those of gray cast iron and with operating characteristics superior to those of malleable iron and high-strength cast iron.
