The pitting resistance of a series of experimental stainless steels with varying amounts of nickel, chromium, molybdenum, manganese and nitrogen and a number of commercial stainless steels and nickel based alloys has been studied in highly concentrated chloride media. The results suggest that nitrogen enhances the pitting resistance of stainless steel and exceptional corrosion resistance is achieved with high levels of nitrogen in combination with suitable amounts of molybdenum and chromium. For example, an alloy with 20% nickel, 24% chromium, 6% molybdenum, 0.44% nitrogen and balance iron exhibits corrosion resistance noticeably better than Hastelloy G and at least as good as Hastelloy C-276 in the environments investigated.
