S31254 Stainless Steel Flanges A182 F44 S31254 LJ Flanges
The blind flanges come in different types such as the SMO 254 Spectacle Blind Flange as well. Each different type of flange has a purpose to serve in an application. The face type of the flanges vary as well.
254 SMo / EN 1.4547 / UNS S31254 / 6Mo super austenitic steel combines moderate tensile strength and high ductility with excellent corrosion resistance in seawater and variety of industrial environment. Typically the alloy has PREN of 42 ¨C 44, which ensure that the resistance to pitting corrosion is high and it also has a hight resistance to crevice corrosion. 254SMO is an austenitic steel designed for maximum resistance to pitting and crevice corrosion. Our flanges conform to international dimension standards such as ASME / ANSI B16.5, ASME B16.47 / API 605, ASME / ANSI B16.36, ASME B16.48 / API 590, MSS-SP-44, BS 3293, API 6A and DIN. With high levels of chromium, molybdenum and nitrogen, 254SMO is especially suited for high chloride environments such as brackish water, seawater, pulp mill bleach plants and other high-chloride process streams.
