COMPOSITE THREADED TUBULAR CONNECTOR ABSTRACT OF THE DISCLOSURE Improved threaded tubular connectors, such as tool joints and the like, for tubular oilfield products are prepared by joining two dissimilar metallic billets together, as by welding or the like; to produce a composite billet. The composite billet is then forged and pierced to produce a bimetallic rough forging which is subsequently neat treated and machined to produce the desired tubular connector, e.g. tool joint. One of the dissimilar metallic billets is of a metal or alloy of the type commonly used for the final product and the other metallic billet is of a metal or alloy selected for its desirable characteristics of strength and/or corrosion resistance.
