PROCESS FOR PRODUCING STEEL WIRES FOR THE MANUFACTURE OF FLEXIBLE PIPES, STEEL WIRES OBTAINED THEREBY, AND FLEXIBLE PIPES REINFORCED BY SUCH WIRES.

摘要

P It is characterized in that it consists at least in subjecting a continuous wire of great length and constant cross section hardening and heat treatment whose temperature and duration conditions are such that regardless of the content in initial carbon, the steel wire thus treated has a lower yield strength than it would have in the cold worked state and a structure having little free ferrite. BR/ Application in particular to the manufacture of steel wires compatible with H2 S. / P
