METHOD OF MAKING COBALT-BASED ALLOY TUBES HAVING ENHANCED MECHANICAL PERFORMANCE CHARACTERISTICS AND A TUBE FORMED BY THE METHOD

摘要

A method for the manufacture of cobalt-based tubes is provided, wherein cobalt alloy strips are formed into tubes, and the drawn tubes are subjected to hardening and/or stress relieving by heat treatment. A synergistic effect of the material composition, the tube drawing and the heat-treatment process results in production of tubes with significantly enhanced mechanical performance attributes.
