DUAL-PHASE STAINLESS STEEL WIRE ROPE HAVING HIGH FATIGUE RESISTANCE AND CORROSION RESISTANCE

摘要

The invention relates to a two-phase stainless steel wire rope having a high fatigue resistance and a high corrosion resistance comprising two-phase stainless steel wires of 0.1 % by weight or less of C, 1.0 % by weight or less of Si, 1.5 % by weight or less of Mn, 0.04 % by weight or less of P, 0.03 % by weight or less of S, 18.0 to 30.0 % by weight of Cr, 3.0 to 8.0 % by weight of Ni, 0.1 to 3.0 % by weight of Mo and the balance of Fe, wherein the volume ratio of ferrite is 30.0 to 80.0 % and the wires are controlled to have a mean slenderness ratio (MR value) of 4 to 20 by wire drawing. The wire rope of the invention is suitable for dynamic uses such as a rope for an elevator or a skilift.
