ABSTRACT:
A billet is provided for subsequent heating and working into a finished product in, for example, a rolling mill. The billet comprises a mass of swarf jacketed in a tubular jacket. At least one end of the jacket is joined to an end piece which surrounds the end of the mass of swarf. The end piece and the jacket are materials of different composition. In particular, a jacket of stainless steel with mild steel end pieces at each end is envisaged. The end pieces may be open ended sleeves or caps. Where an open ended sleeve is used it may be closed by crimping its end or by the provision of an insert which is welded or crimped into the sleeve. The end of the swarf exposed in the sleeve may also be sealed by application of a graphite paste.
