UNS S20910, XM-19
Nitronic ® 50 is an austenitic stainless steel alloy that combines corrosion resistance with very high strength. The resistance to corrosion is better than plain stainless 316, but the yield is twice as high at room temperature. Unlike other stainless alloys remains Nitronic ® 50 non-magnetic after cold working. The alloy is used for, among other things, shafts and valves.
