In casting of metal on a pre-made work piece which pre-made work piece and casting material is done mechanical and metallic bonding in the state of transition phase each other, work piece is composed of c 3.0 wt% (in the case of maximum), Si 1.7-2.2 wt%, Mn 1.0-1.5 wt%, Ni 18-22 wt%, Cr 1.8-2.4 wt%, Nb 0.1 wt%, Mg 0.05 wt%, and the rest is Fe alloy, it is inserted into transition region of work piece. Mechanical bonding is obtained by planning dove-tail groove and expanding the expansion part, and metallic bonding is obtained by dissolving the dissolving part when dissolving cast iron is poured.
