S31803 fasteners 2205 duplex structural bolt
UNS S31803 Bolted Fasteners are used in marine, agricultural, chemical, construction, shipping, aviation, nuclear and industrial equipment.
Duplex Nuts, Duplex Bolts, Duplex Studs, Duplex Washers and Duplex Screws. These duplex steel UNS S31803 fasteners are often referred to as workhorse grades and are the most widely used grade in the duplex stainless steel family. The yield strength of this alloy is almost twice that of conventional austenitic stainless steel alloys. Therefore, duplex fastener manufacturers will recommend these fasteners as ideal components for assembly in applications requiring high strength and good corrosion resistance.
