ASTM A182 Duplex Stainless Steel Flanges provides both high strength and excellent corrosion resistance
S31803 has been supplemented by S32205 which has a higher minimum N, CR and Mo.
ASTM A182 UNS S31803 Duplex Flanges, 2205 Ferritic Stainless Steel Flanges are known to deliver exceptional performance and are generally developed for meeting the demands. In both resistance and strength, they find an excellent application. ASTM A182 Grade F51 Duplex Steel is not generally suitable for use at temperatures above 300 Degree C as it suffers from precipitation neither of brittle micro constituents, nor below -50 Degree C because of its ductile-to-brittle-transition. Duplex Flangs for better corrosion resistance, ASTM A182 F51 UNS S31803.
