Nitrogen alloyed, Ni-free, austenitic stainless steels with more than 1 wt.% nitrogen are a new group of alloys with promising properties. They exhibit a very interesting combination of high strength and toughness with a high corrosion resistance in various environments. This work shows the influence of chromium, molybdenum and nitrogen on the corrosion resistance of Fe25Mn-alloys. According to these results Fe25Mn-alloys with approximately 20 wt.% chromium about 3 wt.% molybdenum and approximately 1.3 wt.% nitrogen have an excellent corrosion resistance. The critical pitting temperature (CPT) of 61 C and the critical crevice temperature (CCT) of 37 C when tested according to ASTM G-48 A were significantly higher than the well established AISI 316 L stainless steel.
