NITRONIC 50
General
This alloy is an austenitic, nitrogen strengthened steel combining corrosion resistance comparable with 316 stainless and greater strength. It is readily fabricated and remains non-magnetic even after severe forming operations. In many areas, it outperforms types 316 and 317 with almost double the yield strength.
Generally found in applications requiring high strength and corrosion resistance such as fasteners, boat shafting, marine hardware, pumps and valves.
