Nitronic 50 (XM - 19 / FXM - 19) S20910 stainless steel, Nitronic 50 (XM - 19 / FXM - 19) S20910 is a nitrogen strengthened austenitic stainless steel, its corrosion resistance is better than 316, 616 l, 317 l, 317, and yield strength at room temperature and is almost twice as much.The steel in high temperature and minus temperature has a very good mechanical properties.S20910 even after large cold deformation or in minus temperature can keep low permeability and at the same time in 1200 ℉ (649 ℃) temperature has very good mechanical properties.Although S20910 in low temperature environment can maintain very low magnetic conductivity, but also cannot achieve Nitronic 33 and Nitronic 40 levels.A lot of technological process of S20910 embodies the outstanding corrosion resistance.After about 2025 ℉ (2025 ℃) annealing treatment, S20910 even after welding condition can in high corrosion environment show excellent corrosion resistance.The steel grade in resistance to sulfide stress corrosion cracking and intergranular corrosion resistance is very outstanding performance.S20910 to withstand prolonged exposure in the Marine atmosphere environment, has proved its corrosion resistant performance in static water environment to be slightly better than Monel 400 (UNS N04400).The steel grade will be affected by the stress corrosion cracking in the nitride environment, in terms of cracking resistance between 304 and 316.Petroleum, petrochemical, chemical, fertilizer, nuclear fuel recycling, pulp and paper industry, textile, food processing and sea use efficient alloy.Using highly corrosion-resistant and high strength NITRONICS 50 stainless steel components, including pumps, valves and fittings, fasteners, wire, chain link, screen and wire coat, Marine hardware, such as ship, pump shaft, heat exchanger, spring and photographic equipment.
