Ninthore Overseas is One Of The Leading Manufacturer And Exporter of Alloy Steel F5 Flanges, which may also be utilized at increased temperatures. The energy consumption based on the production of these Alloy Steel F5 Slip On Flanges has decreased recently due to technological improvements and energy conservation measures. This also influences its use in commercial kitchens and food processing plants, as our Alloy Steel F5 Threaded Flanges can be steam – cleaned and sterilized and does not need paint or other surface finishes. These Alloy Steel F5 Weld Neck Flanges is often applied in areas of higher temperatures than stainless steel can endure, and its low carbon allows it to be resistant against carbon precipitation.

However, like many other steels, our Alloy Steel F5 Blind Flanges is susceptible to warm chlorine environments and can potential pit and crack. These Alloy Steel F5 Socket Weld Flanges provides outstanding corrosion resistance in, for instance, caustic and acidic applications which includes sulphuric and higher chloride environments.

This is exactly because of the outstanding resistance to sulphide cracking of our Alloy Steel F5 Lap Joint Flanges in conditions characterized by increased levels of hydrogen sulphide (H2S), carbon dioxide (CO2) and as well chlorides (Cl). The major iron – bearing raw materials for making accessories of these Alloy Steel F5 Ring Joint Type Flanges are blast – furnace iron, steel scrap, and direct – reduced iron (DRI).
