MANUFACTURE OF NONMAGNETIC STEEL WIRE

PURPOSE:To manufacture a high-strength high-Mn nonmagnetic steel wire at a low cost by hot rolling a steel contg. specified percentages of C, Si, Mn, Ni, Cr and N under specified conditions and by cold drawing the resulting wire rod. CONSTITUTION:A steel consisting of, by weight, 0.01-0.50% C, =70%...

Zusammenfassung:	PURPOSE:To manufacture a high-strength high-Mn nonmagnetic steel wire at a low cost by hot rolling a steel contg. specified percentages of C, Si, Mn, Ni, Cr and N under specified conditions and by cold drawing the resulting wire rod. CONSTITUTION:A steel consisting of, by weight, 0.01-0.50% C, =70% reduction of area, 900-1,000 deg.C coiling temp. and >=5 deg.C/sec cooling rate after coiling. The resulting wire rod is directly cold drawing at >=55% reduction of area without carrying out soln. heat treatment. A nonmagnetic steel wire having high strength such as >=180kg/mm tensile strength and superior corrosion resistance is obtd.
