Abstract:
1. A method for producing a clad stainless steel, the method comprising hot rolling a welded assembly to provide a hot rolled band, the welded assembly comprising a stainless steel plate welded to an alloy cladding material plate, the cladding material plate being disposed in a recess on a surface of the stainless steel plate such that a projecting portion of the stainless steel plate defines the recess and surrounds and is directly against the entire peripheral edge of the cladding material plate and defines a seam between the entire peripheral edge of the cladding material plate and the projecting portion of the stainless steel plate, wherein the welded assembly is welded together completely around the seam, wherein in the welded assembly a surface of the cladding material plate is substantially coplanar with a surface of the projecting portion of the stainless steel plate, the projecting portion of the stainless steel plate inhibits the alloy cladding material from spreading beyond an edge of the stainless steel during the hot rolling, and at the hot rolling temperature the hot strength of the alloy cladding material is less than the hot strength of the stainless steel.
