ABSTRACT:
In a method of bonding ferric and austenitic dual stainless steels, an insert material made of a Ni base alloy having a melting point below 1290.degree. C. is put between the bonding cross section faces of mother material steels comprising a dual phase stainless steel. A pressure force in the range of 3 MPa to 5 MPa is applied to a bonding area. The bonding area is heated at a temperature in the range of 1290.degree. C. to a melting point of the mother material steel. The temperature is kept for in the range of 30 second to 180 second.
