Nitronic 50 is a nitrogen-strengthened austenitic stainless steel that has properties that combine excellent strength, ductility, toughness, corrosion resistance and fabricability. Nitronic 50 is a very versitile and useful alloy due to it retaining its very good mechanical properties at both elevated and sub-zero temperatures. Also Nitronic 50 has outstanding corrosion resistance (greater than alloy 316 and 316L) and it is an effective alloy for use in the Petroleum, Chemical, Marine, Nuclear, Pulp and Paper, Textile, Food Processing industries.
