Abstract:
1. A corrosion resistant non-magnetic austenitic stainless steel, comprising: about 17.0 to about 20.0 weight percent chromium, about 0.7 to about 2.5 weight percent copper, about 17.5 to about 19.5 weight percent manganese, about 1.85 to about 3.00 weight percent molybdenum, about 3.5 to about 5.0 weight percent nickel, about 0.55 to about 0.70 weight percent nitrogen, about 0.001 to about 0.5 weight percent of an additional element selected from the group consisting of a rare-earth element, calcium, iridium, osmium, rhenium, rhodium, ruthenium, silver, and a combination thereof wherein the about 0.001 to about 0.5 weight percent is per individual additional element, and iron; wherein all the amounts are in weight percent based on the total weight of the non-magnetic austenitic stainless steel; and wherein the non-magnetic austenitic stainless steel has corrosion fatigue resistance and pitting corrosion resistance.
