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.
A method for producing a clad product, the method comprising:
The method of claim 23, wherein the cold rolled strip is bright annealed intermediate at least two successive steps of cold rolling.
A method for producing a clad stainless steel, the method comprising:
The method of claim 31, wherein the cladding material is nickel, the stainless steel plate is T-316L stainless steel, and the one or more framing elements are one of T-316L stainless steel and T-304 stainless steel.
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 a plate of an alloy cladding material, the plate of cladding material 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 the peripheral edge of the plate of cladding material, wherein the projecting portion of the stainless steel plate inhibits the cladding material from spreading beyond an edge of the stainless steel during the hot rolling.
A method of making a dual clad stainless steel strip, the method comprising:
A method of making an article of manufacture, the method comprising:
A welded assembly useful in the production of clad products, the welded assembly comprising a cladding material disposed on a substrate material, both the substrate material and the cladding material being an individually selected alloy, wherein in the welded assembly at least a first edge of the cladding material does not extend to a first edge of the substrate material and thereby provides a margin between the first edges, and wherein an alloy having hot strength greater than the cladding material is within the margin and adjacent the first edge of the cladding material.
A welded assembly useful for producing a clad product, the welded assembly comprising:
