Abstract

A method for manufacturing a strand from a stainless steel by cold forming a billet into the cold-hardened strand and subsequently annealing the strand is provided. The method allows stainless steel strands to be produced, which have both a high tensile strength, as well as a high degree of elongation. The strand is heated to a temperature ranging from 400° C. to 460° C. while the strand is being annealed, and the cold-hardened strand is surrounded by a protective gas atmosphere during the heating process.
