Zusammenfassung:Provided is a lean duplex stainless steel having excellent bending processability. The lean duplex stainless steel includes, in percent (%) by weight of the entire composition, 0.01 to 0.06 % of carbon (C), 0.2 to 1.0 % of silicon (Si), 3.5 to 6.5 % of manganese (Mn), 18.5 to 22.5 % of chromium (Cr), 0.05 to 0.25 % of nitrogen (N), and the remainder of iron (Fe) and other inevitable impurities, wherein a sum of amounts of Cr and Mn is from 26.0 to 28.5 % and a Cr/Mn ratio is from 3.4 to 4.1.
