Ninthore Overseas is one Of The Leading Manufacturer And Exporter of Monel Alloy K500 Flanges, which are manufactured under the supervision of our experienced professionals. Monel K500 Threaded Flanges (UNS N05500) has resistant to a sour – gas environment. Monel K500 Slip On Flanges is often used in Chemical Process Industry: such as in processes involving organic acids, caustic soda and dry chlorine, production of chlorinated plastics, and more. The corrosion resistance of Monel K500 Weld Neck Flanges is substantially equivalent to that of alloy 400 Weld Neck Flanges except that, when in the age – hardened condition, it has a greater tendency toward stress – corrosion cracking in some environments.

The best machinability for these Monel K500 Lap Joint Flanges is in the annealed condition. Meanwhile, these Monel K500 Socket Weld Flanges are also being offered in different sizes and shapes to our customers. The levels of molybdenum and copper enable Monel K500 Ring Joint Type Flanges to resist reducing agents and acids. Chromium in Monel K500 Spectacle Blind Flanges gives resistance to oxidizing conditions, such as nitric acid solutions, nitrates and oxidizing salts.

The chemical composition of Monel K500 Nippon Flanges provides great resistance to a lot of corrosive environments, such as pitting, crevice corrosion, inter – granular corrosion, and stress – corrosion cracking. Monel K500 Spacer Flanges has useful resistance to boiling sulfuric acid up to 40 % concentration, to 60 % concentration at 176 Degree F and in all concentrations to 150 Degree F.
