  In the present work, attempts were made to develop a new type of cast iron, stainless spheroidal carbide cast iron whose chemical composition is x%C-20%Cr-10%Ni-y%V-Fe. This cast iron exhibits excellent characteristics in corrosion and abrasive resistance. In this cast iron, the morphology of vanadium-carbide was observed to change depending on melting conditions. At relatively higher temperature such as 2023K spheroidal carbides crystallized, while flower-like carbides crystallized at relatively lower temperature such as 1723K. Spheroidal carbide particles have a tendency to coagulate with each other when the temperature decreases and appear flower-like. These flower-like particles were found to break down to spheroidal particles again when the temperature was elevated. Thus we can conclude that the morphology of vanadium-carbide is not affected by the thermal history, but depends only on the pouring temperature.
