Austenite-ferrite corrosion-resistant steel for high-strength wire

Austenite-ferrite steel of grade 03Kh13N10K5M3Yu2T with strain-induced unst able austenite is investigated. It is shown that the steel is quite suitabl e for the production of thin and very thin wire 0.15 - 0.8 mm in diameter w ith a high strength and satisfactory ductility. The optimum treatment of su ch wire includes water quenching from 1000 degreesC, cold plastic deformati on with a degree of 80%, and 1-h aging at 500 degreesC. The strain-induced martensite is shown to possess a high susceptibility of strain aging.
