ABSTRACT:
A clad metal comprising at least one layer of rephosphorized carbon steel metallurgically bonded to at least one layer of stainless steel. In a preferred embodiment the rephosphorized carbon steel layer comprises at least about 0.05 weight percent phosphorus and the stainless steel layer comprises a type 444 stainless steel. A clad metal made in accordance with the present invention may be produced into any one of a variety of shaped, configurations or parts including, for example, slabs, blooms, sheet strip or finished parts. Once the clad metal has been produced by forming a metallurgical bond between the various components thereof, the clad metal may be subjected to further processing including, for example, forging, stamping, rolling, welding, machining, and the like. The invention further provides a unique parting compound for use in the production of clad metals which are clad on only one side. Such parting compound comprises a mixture of levigated alumina and an inert binder. Preferably, the inert binder comprises water glass.
