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.

Abstract: A crucible for containing molten magnesium, and a process for forming the crucible. The crucible is formed from ferritic stainless steel, and particularly type 444 stainless steel plate. The method involves forming ferritic stainless steel plate into component parts of the crucible, while maintaining the ferritic stainless steel plate at temperatures above about 200.degree. F. but below the "blue brittle" temperature range. Further, the method involves special techniques for welding the crucible parts. Specifically, the crucible parts are preheated to a temperature of 100.degree. -150.degree. C. and are completely welded by a process utilizing multiple welding passes with a special metal inert gas shielded welding technique before any cool down of the crucible parts below 100.degree. C. is allowed. The welds extend completely through the crucible walls, which are the thickness of steel plate, and completely incorporate the crucible parts while being essentially free of cracks.

Abstract: The invention relates to a clevis structure having transverse pins for a universal coupling effect. The structure is an assembly of mechanically interlocking components which can be individually fabricated and releasably joined without load carrying fasteners, welding, or the like. The components are readily fabricated even in relatively large sizes.
