The present invention relates to stainless spheroidal carbide cast iron is such: comprises Fe as its main component;, C 0.6~4.0% and V 4~15% as its necessary components, P 0.01~0.15%, S 0.01~0.05%, and Al 0.05~1.0% as bubble assistants, and Ni 4~15%, Si 0.2~4.5%, Cr 13~30%, and Mn 0.2~1.5% as anticorrosion matrix formers in weight %; produced by the process that minute spheroidal space of gas (hydrogen) bubble is dispersed substantially equally into molten metal positively by high temperature melting at 1950~2073 K which is the bubbling reaction temperature, and spheroidal vanadium carbide of a covalent bond is crystallized inside of the spheroidal space, which has special characteristics such as corrosion-resistance, heat-resistance, abrasion-resistance, thoughness and processing ability. Such improving its characteristics such as heat-resistance and corrosion-resistance can be applied within a wide areas of industries such as chemical industry, machinery, shipping and petrochemical industry which efficiency and functions are getting high in accordance with the development of the industries.
