Mahavir India is an accredited manufacturer and exporter of Duplex Steel F51 / F52 Flanges, which is very ductile and has good weldability enabling its widespread usage in many applications. Duplex Steel F51 Slip On Flanges, combining excellent high temperature properties with good ductility and weldability, are designed for high temperature service. The strength of Duplex Steel F52 Blind Flanges is a combination of good strength and corrosion resistance in temperatures up to 2100 Degree F (1149 Degree C). Duplex Steel F51 Spectacle Blind Flanges is typically used for elevated temperature applications as its high chromium and nickel content provide solid corrosion resistance, excellent resistance to oxidation, and as said superior strength in temperatures up to 2100 Degree F. Because of its high chromium and moderate nickel content, Duplex Steel F52 Weld Neck Flanges is resistant to sulfidation and can also be used in moderately carburizing atmospheres.
The high chromium and nickel contents of Duplex Steel F51 Socket Weld Flanges provide comparable corrosion resistance, superior resistance to oxidation and the retention of a larger fraction of room temperature strength than the common austenitic alloys. Duplex Steel F52 Lap Joint Flanges can also be used for welding air hardening steels such as armour plate and for welding base metals of unknown composition, as well as dissimilar metals. In intermittent service, Duplex Steel F51 Ring Type Joint Flanges can be used at temperatures up to 1030 Degree C as it resists scaling and has a relatively low coefficient of expansion.
