Tin, antimoni, mangan, molibdiyɔmu, kromiyɔmu, vanadiyɔmu ani niobium be se ka grafiti sanji n’a yiriwali bali, ka karbɔniw dilan, ani bɛɛ be sɔrɔ karbɔniw la minw basiginin lo ɲɔgɔn kan. Molybdenum ka nɔɔ be taga n’a farankan hakɛ ye,<0.8%, the effect of molybdenum is mild, which is to make the pearlite refinement, the content is the carburization stable element. It is generally believed that the role of manganese is to increase the amount of cast iron beads and improve the strength of cast iron. In fact, manganese is also multifaceted, when the content is high, it will make the graphite thick, thus reducing the strength of cast iron.
