The Performance Characteristics Of：
(1)The corrosion resistance is better than 316L and 317L stainless steel. It can be exposed to the Marine atmosphere for a long time. In the quiet sea water environment, the corrosion resistance performance is slightly better than [SCALE STEEL]Monel 400 alloy.
(2) double the tensile strength of 304 and 316 stainless steel.
(3) It is affected by stress corrosion cracking in hot chloride environment, and its cracking resistance is between [SCALE STEEL]304 and 316.
(4)It still maintains excellent mechanical properties at 629℃.
(5)Good mechanical properties at low temperature, very low permeability.
Nitronic 50 has both high corrosion resistance and high strength. It is a highly efficient alloy for petroleum, [SCALE STEEL]chemical, fertilizer, nuclear fuel recovery, pulp and paper making, textile, food processing, Marine and other industries. Typical applications include: sea pump shaft, heat exchanger, pressure vessel, Marine engineering hardware, etc.
