SS 904L Long Weld Neck Flanges

We are one of the well-known trading houses for SS 904L long Flanges, where fractional distillation of tall oil often needs better material or even the more frequently used. In these hot concentrated caustic solutions, the corrosion resistance of these Stainless Steel 904L Slip On Flanges is mainly determined by the nickel content of the material. With a nickel content of 25 %, Stainless Steel 904L Threaded Flanges has proven to be a good alternative to most conventional stainless steels. Conventional stainless steels such as these Stainless Steel UNS N08904 Weld Neck Flanges are susceptible to chloride stress corrosion cracking (SSC) under certain conditions. Resistance to SSC in Stainless Steel 904L Blind Flanges increases with the increased content of nickel and molybdenum. Therefore, the higher performance austenitic stainless steels such as these Stainless Steel 904L Socket Weld Flanges have very good resistance to SSC. Stainless Steel 904L Lap Joint Flanges shows resistance to SSC in a chloride solution under evaporative conditions, where high performance austenitic steels clearly outperform. These Stainless Steel 904L Ring Joint Type Flanges can be easily welded and processed by standard shop fabrication practices. Working temperatures of 1562 Degree F – 2102 Degree F (850 Degree C – 1150 Degree C) in Stainless Steel 904L Spectacle Blind Flanges are recommended for hot working processes. These Stainless Steel 904L Nippo Flanges should be solution annealed at 1940 Degree F – 2084 Degree F (1060 Degree C – 1140 Degree C).
