Duplex steel UNS S31803 fasteners are fastening components made from a specific grade of duplex stainless steel known as UNS S31803. This steel grade is also commonly referred to as 2205 stainless steel. UNS S31803 is duplex stainless steel with a combination of austenite and ferrite phases in its microstructure, providing excellent corrosion resistance and high strength. It offers superior resistance to general corrosion, pitting, and crevice corrosion, making it suitable for aggressive environments.

Duplex Steel UNS S31803 Fasteners are manufactured by cutting and shaping the raw material, followed by forming, threading, and heat treatment processes. Surface finishing is applied for enhanced appearance and corrosion resistance. Inspection and quality assurance ensure the fasteners meet specifications.
