Nitronic® 50 is a nitrogen-strengthened austenitic stainless steel that possesses corrosion resistance superior to 316, 316l, 317 and 317l plus approximately twice the yield strength at room temperature. it has very good mechanical properties at both elevated and sub-zero temperatures. The alloy retains low magnetic permeability even after severe cold working or exposure to sub-zero temperatures and excellent mechanical properties up to 1200˚F (629˚C). Nitronic® 50 provides outstanding corrosion resistance in many process streams. Annealed at 2025˚F, Nitronic® 50 exhibits excellent resistance to highly corrosive environments where the material will be used in the as-welded condition. it has outstanding resistance to sulfide stress cracking and to intergranular attack. Nitronic® 50 will withstand prolonged exposure to marine atmospheres. it has also been found to perform somewhat better than eC400 (UNS N04400) in quiet seawater. like most stainless steels, Nitronic® 50 may suffer stress corrosion cracking in hot chloride environments. it is ranked between 304 and 316 in resistance to cracking. Nitronic® 50 does not become magnetic when severely cold worked. This makes it useful for applications requiring a combination of excellent corrosion resistance and low magnetic permeability. Although the magnetic permeability of Nitronic® 50 remains very low at cryogenic temperatures
