Inconel 825 Flanges Manufacturer and Exporter
The Inconel 825 Flanges are flanges made of a nickel-iron-chromium alloy that is highly resistant to oxidation, reduction, acids, and stress corrosion cracking in harsh industrial applications. They are ideal for chemical processing, marine, oil & gas, pollution control applications and are able to resist pitting, crevice corrosion, sulfuric acid, phosphoric acid and chloride attack. They are more resistant to corrosion, weldable, and thermally stable in a broad temperature range, including the cryogenic and high temperature range. Inconel 825 Flanges are also highly robust and strong for high-demand pipelines. Amardeep Steel Centre is a trusted manufacturer and supplier of top-notch quality Inconel 825 Flanges with precision-engineered products available in several dimensions, pressure classes and international standards for all over the world industrial applications.
