<p>The present invention relates to a method of manufacturing supper austenitic stainless steel having superior corrosion resistance. The method of manufacturing supper austenitic stainless steel having superior corrosion resistance according to an embodiment of the present invention includes the steps of performing strip casting and heat treatment of molten steel having an adjusted composition, performing intermediate rolling of the heat-treated strip, and producing a hot-rolled coil; cold-rolling the hot-rolled coil, and primarily annealing the cold-rolled coil to remove the remaining stress; raising the temperature of the cold-rolled coil, which has been subject to the primarily annealing process, to a target temperature; and secondarily annealing the cold-rolled coil while applying annealing tensile stress in the range of 2.0-3.0 kgf/mm^2 to the cold-rolled coil at the target temperature.</p> |
