摘要
A high strength, high ductility, low carbon, dual phase steel wire, bar or rod and process for making the same. The steel wire, bar or rod is produced by cold drawing to the desired diameter in a single multipass operation a low carbon steel composition characterized by a duplex microstructure consisting essentially of a strong second phase dispersed in a soft ferrite matrix with a microstructure and morphology having sufficient cold formability to allow reductions in cross-sectional area of up to about 99.9 %. Tensile strengths of at least 120 ksi to over 400 ksi may be obtained.
