Super Duplex UNS S32760 ASTM A182 F55 Weld Neck Flange | UNS S32760 bridas | 1.4501
Super Duplex UNS-S32760 -A182-F55 , Super Duplex Alloy UNS S32760 (F55 / 1.4501) has excellent resistance Pitting and Crevice Corrosion in seawater at elevated temperatures, supplied with a PREN 40<( Pitting Resistance Eqv) . Excellent resistance to SCC ( Stress Corrosion Cracking) in Sour and Chloride environments .
Super Duplex UNS S32760 Weld Neck Flanges, manufactured in accordance with ASTM A182 Grade F55, are designed for high-pressure and highly corrosive environments.
Featuring a high alloy content with chromium, molybdenum, and nitrogen, F55 weld neck flanges offer exceptional strength and superior resistance to pitting, crevice corrosion, and stress corrosion cracking.
What Is Super Duplex UNS S32760 (F55)?
UNS S32760, also known as Super Duplex Stainless Steel F55, is a high-performance duplex stainless steel with a balanced austenitic–ferritic microstructure.
Compared with standard duplex grades, S32760 provides improved corrosion resistance, particularly in chloride-rich and seawater environments.
UNS S32760 is commonly specified when UNS S32750 (F53) may not offer sufficient corrosion resistance.
Providing higher strengths than both austenitic and 22% Cr Duplex Stainless Steels UNS S32760 (F55) is suited to a variety of applications in industries such as Oil & Gas, CPI(Chemical Processing Industries), and Marine environments.
