Features
Broad Corrosion Resistance: Resistant to sulfuric acid (up to 50% concentration at 150°C), hydrochloric acid (up to 8% at 60°C), seawater, and chloride solutions, outperforming 316L and even some duplex steels in aggressive media.
High-Temperature Performance: Maintains mechanical properties from -196°C to 550°C, with excellent resistance to intergranular corrosion and oxidation in both reducing and weakly oxidizing conditions.
Low Magnetic Permeability & Thermal Conductivity: Suitable for applications requiring non-magnetic components (e.g., marine sensors) and efficient heat transfer in heat exchangers.
Superior Fabricability: Readily weldable with ERNiCrMo-3 filler metal, and formable via cold or hot working, though post-weld heat treatment is unnecessary unless specified for critical SCC environments.
Application
Offshore Oil & Gas: Used in seawater injection systems, subsea pipelines, and gas sweetening units, resisting chloride-induced SCC and H2S corrosion in sour gas environments.
Chemical Processing: Handles sulfuric acid pickling baths, phosphate fertilizers, and organic solvents in reactors, evaporators, and pipelines.
Desalination Plants: Ideal for heat exchanger tubes in multi-stage flash (MSF) and reverse osmosis (RO) systems, enduring high-temperature seawater and brine.
Nuclear Industry: Employed in spent fuel pools and primary coolant systems due to its resistance to radiation-induced corrosion and low activation properties.
