Abstract


Different commercial steel scraps have been selected so as to analyse the outcome of their use as raw materials and to evaluate their applicability in the production of ductile iron castings. These selected steels show an important chemical variability mainly depending on their origin and on their previous utilisation. According to that, alloying elements added through these materials have been determined and their effects on the structural characteristics and the mechanical properties of test-castings with different shape and size have been studied. The most important element added is manganese, which is included in all the selected scraps with contents higher than 0.2 %. Other elements are: copper, chromium, tin, titanium and vanadium. All of them are known as pearlite promoters apart from titanium and vanadium. Therefore, these elements can be used for manufacturing casting containing pearlitic and/or mixed ferritic and pearlitic structures. No carbides were found in all the test castings.
