Abstract
The present invention provides: a ferritic stainless steel cast iron including: Fe as a main component; C: 0.20 to 0.40 mass %; Si: 1.00 to 3.00 mass %; Mn: 0.30 to 3.00 mass %; Cr: 12.0 to 30.0 mass %; and one of Nb and V, or both of Nb and V in total: 1.0 to 5.0 mass %, the ferritic stainless steel cast iron satisfying the following formula (1):1400≦1562.3−{133WC+14WSi+5WMn+10(WNb+WV)}≦1480  (1)wherein, WC (mass %), WSi (mass %), WMn (mass %), WCr (mass %), WNb (mass %), WV (mass %) and WCu (mass %) are contents of C, Si, Mn, Cr, Nb, V and Cu, respectively; a process for producing a cast part from the ferritic cast steel; and the cast part.
