Fitwel Industries LLP is a leading ISO certified company deal in duplex steel blind flanges And Super Duplex Blind Flanges. Duplex Steel is highly resistive metal, Another reason why BLRF Flange Supplier in Mumbai recommends using components made from this grade of Duplex steel is that they display very good stress corrosion cracking (SCC) resistance. This is a property the ASME b16.5 Duplex Blind Flange has been inherited from the Ferritic side of the stainless steel. SCC could be a problem under certain circumstances like humidity & elevated temperature or environments containing certain chemicals such as chlorides, for standard austenitic stainless steel grades such as Types 304 and 316. Therefore, Duplex Blind Flange Suppliers often supply them to industries such as oil & gas, petrochemicals as well as marine industries. For example, Duplex Blind Flange Manufacturer note that the flanges made from this grade of stainless steel often outperform many stainless steel grades.
