Inconel 800 Flanges are manufactured from an alloy that consists of nickel, iron and chromium and is known for its high strength, resistance against oxidation and thermal stability. These flanges are used in heat exchanger, petrochemical plants, power generation plants, furnaces, etc, where carburization and corrosion protection is needed. Inconel 800 Flanges possess exceptional weldability properties and superior mechanical properties which enable them to be used in challenging pipe lines in the industry. The Inconel 800 Flanges that we manufacture and supply are: Welding neck, Slip-on, Blind, Socket welding and Lap joints.
Amardeep Steel is one of the leading manufacturer and supplier companies of Inconel 800 Flanges that are available in various sizes and dimensions as per international standards and deliver in different parts of the indian as well as internationally.Each flange is supplied with EN 10204 3.1/3.2 MTC, PMI reports, dimensional inspection, and third-party inspection support on request. We also supply 800H and 800HT variants for elevated-temperature creep-strength applications where standard Alloy 800 is not sufficient.
