Abstract

A method for producing a single-clad or multiple-clad product includes providing a welded assembly comprising a cladding material disposed on a substrate material. Both the substrate material and the cladding material are individually selected alloys. At least a first edge of the cladding material of the welded assembly does not extend to a first edge of the substrate material and thereby provides a margin between the first edges. A material that is an alloy having hot strength greater than the cladding material is within the margin and adjacent the first edge of the cladding material. The welded assembly is hot rolled to provide a hot rolled band, and the material within the margin inhibits the cladding material from spreading beyond the edge of the substrate material during the hot rolling. In certain embodiments of the methods, the substrate material is stainless steel and the cladding material is nickel or a nickel alloy.

Dependent claims

A method for producing a clad product, the method comprising:

providing a welded assembly comprising an alloy cladding material plate disposed on a steel plate, and one or more framing elements of an alloy material comprising a hot strength greater than the cladding material plate,
wherein in the welded assembly a peripheral edge of the cladding material plate does not at any point extend to a peripheral edge of the steel plate, thereby defining a margin between the peripheral edge of the cladding material plate and the peripheral edge of the steel plate,
wherein each framing element is disposed in the margin and is directly against the peripheral edge of the cladding material plate and defines a seam between the framing elements and the entire peripheral edge of the cladding material plate, and the alloy material and the cladding material plate are welded together along the seam;
and
wherein each framing element extends to the peripheral edge of the steel plate and is welded to the steel plate;
and
wherein in the welded assembly, a surface of the cladding material plate is substantially coplanar with a surface of the each framing element disposed in the margin;
and
hot rolling the welded assembly to provide a hot rolled band, wherein each framing element inhibits the cladding material plate from spreading beyond the edge of the steel plate during the hot rolling.
