    摘要： An austenitic stainless steel having good corrosion resistance, particularly in chloride environments; this is achieved by the use of a rare earth element, preferably lanthanum, singly or in combination with nitrogen, along with nickel and molybdenum at relatively low levels for an austenitic stainless steel. The composition includes 15 to 25% chromium, greater than 16 to 25% nickel, 3 to 7% molybdenum, with a rare earth element consisting of lanthanum within the range of 0.005 to 0.05% in combination with 0.1 to 0.5% nitrogen.
