Duplex Steel S31803 Instrumentation Accessories
The microstructure of the duplex steel is 50/50 austenitic and ferritic, and it is designated as UNS S31803 in the unified numbering system. It is more ductile and has a higher mechanical strength. It provides better corrosion resistance in a variety of cyclic settings, from mild to high concentricity. Duplex Steel UNS S31803 Instrumentation Accessories can be used in situations with pitting and crevice corrosion.
