Clad steel

Clad steel is also referred to as compound steel or sandwich steel. Clad steel is composite materials, made by mill rolling or exploding a thin sheet of a metal that has desired properties over a base ("backing") plate of carbon or alloy steel. The cladding metal may be a stainless steel alloy, nickel or nickel alloy, or copper or copper alloy. The result is a composite with the strength of the backing steel and with corrosion resistance, abrasion resistance of the clad face.

1. For welding of the backing steel use: Basic coated Low Hydrogen electrodes LH-314N or SPECIAL303N. 2. When the steel backing is one layer short of the stainless steel cladding, an over alloyed consumable like 23/14-322 N must be used. Stainless steel

Clad steel with a stainless cladding is found on board some chemical tankers. It is fully weldable if the proper procedure is followed.
