Abstract
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 show 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 alloy G and at least as good as Hastelloy alloy C-276(1) in the environments investigated.Keywords
