Stainless Steel Cladding – Southern Cross Laser

A STAINLESS-STEEL-CLAD metal or alloy
is a composite product consisting of a thin layer of
stainless steel in the form of a veneer integrally
bonded to one or both surfaces of the substrate.
The principal object of such a product is to combine, at low cost, the desirable properties of the
stainless steel cladding and the backing material for applications where full-gage alloy construction is not
required. While the stainless cladding furnishes
the necessary resistance to corrosion, abrasion, or
oxidation, the backing material contributes structural strength and improves the fabricability and
thermal conductivity of the composite. Stainlesssteel-clad metals can be produced in plate, strip,
tube, rod, and wire form.
The principal cladding techniques include hot
roll bonding, cold roll bonding, explosive bonding, centrifugal casting, brazing, and weld overlaying, although adhesive bonding, extrusion, and
hot isostatic pressing have also been used to produce clad metals. With casting, brazing, and welding, one of the metals to be joined is molten when
a metal-to-metal bond is achieved. With hot/cold
roll bonding and explosive bonding, the bond is
achieved by forcing clean oxide-free metal surfaces into intimate contact, which causes a sharing of electrons between the metals. Gaseous
impurities diffuse into the metals, and nondiffusible impurities consolidate by spheroidization.
These non-melting techniques involve some form
of deformation to break up surface oxides, create metal-to-metal contact, and heat in order to
accelerate diffusion. They differ in the amount of
deformation and heat used to form the bond and in
the method of bringing the metals into intimate
contact. Contact us for all your stainless steel works at
