Vessco Overseas is one of the largest exporter, manufacturer and supplier of Stainless Steel 904L Flanges in India. The adding of copper to the setup of 904L helps its appropriateness for constituents, for example, tanks and different merchandise utilized as a part of taking care of phosphoric and sulphuric acid. Meanwhile, the low-slung carbon substance of 904L advances its welding characteristics.This particular grade is an austenitic tempered steel design offering restrained to superior corrosion resistance. Its raised amalgam configurationoffers great consumption and protection from setting in a broad scope of atmospheres.
These flanges have determined service temperatures of 824 degree F (450 degree C). They are as well used for oil refinery components, wiring in electrostatic precipitators, and more. In addition, full annealing must trail any hot work to re-acquire maximum corrosion resistance and ductility. With respect to finest standard quality, we also provide these flanges in different shapes and sizes to our customers. Our UNS NO8904 Flanges is widely utilized as a part of the pharmaceutical, synthetic, gas and oil enterprises. General utilizations of the same incorporate warmth exchangers, tanks, valves, manifolds and flanges
