Super Duplex Fasteners are premium-grade, high-performance fastening components made from super duplex stainless steel, such as UNS S32750 and UNS S32760. These alloys contain a higher content of chromium (24–26%), molybdenum (3–5%), and nitrogen, resulting in exceptional corrosion resistance, mechanical strength, and resistance to pitting, crevice corrosion, and stress corrosion cracking—even in the harshest environments.
Manufactured to international standards like ASTM A182, A479, A276, and NACE MR0175, these fasteners are available in a wide range of types and sizes, including bolts, nuts, studs, washers, screws, and threaded rods.
