Abstract (en)
[origin: WO2016131748A1] The invention relates to a method for producing a strand from stainless steel by cold-forming a bloom into the cold-hardened strand and subsequently annealing the strand. The aim of the invention is to provide a corresponding method for producing a strand from stainless steel, said method allowing stainless steel strands to be produced which have both a high tensile strength as well as a high degree of elongation. According to the invention, this is achieved in that 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.
