About Duplex Steel UNS S31803 Fasteners

Duplex Steel UNS S31803 Fasteners are made from a ferritic-austenitic stainless steel alloy containing 22% chromium and 4 - 6% nickel balanced with additional amounts of molybdenum, manganese, nitrogen, and silicon. This incredible blend of elements allows Duplex Steel UNS S31803 Fasteners to have superior strength and excellent corrosion resistance compared to other commonly available fasteners. Furthermore, the high chromium content allows the surface layer of the fastener to form an insulation barrier against corrosive agents, making them extremely dependable when used outdoors or in humid environments.
