Incoloy 800 Flanges

Incoloy 800 / 800H / 800HT Flanges are high-performance pipe fittings made from nickel-iron-chromium alloys. Incoloy 800 flanges (UNS N08800) resist oxidation, carburization, and scaling at high temperatures. Incoloy 800H flanges (UNS N08810) have higher carbon content, giving improved creep and rupture strength for long term service. Since Incoloy 800HT flanges (UNS N08811) are made with controlled titanium and aluminum they are perfect for extremely hot and corrosive environments. These flanges have a 30% elongation, a tensile strength of 75,000 psi and a yield strength of 30,000 psi. Metracore Alloys is a top manufaacturer of Incoloy 800 flanges in India offering tested and long lasting goods to businesses all over the world.

The flanges are manufactured to ASTM B564 / ASME SB564 standards and are available in sizes from ½” to 48″. Types include threaded, screwed, forged, and plate flanges. Coating options such as zinc plating, oil black paint, or galvanizing provide extra protection against rust. Every flange is tested using ultrasonic flaw detection, hydrostatic testing, X-ray inspection and spectrograph analysis. Excellent corrosion resistance, superior high-temperature strength, improved creep properties and dependable performance under heavy loads are all offered by Incoloy 800 flanges, Incoloy 800H flanges and Incoloy 800HT flanges.

These flanges are widely used in refineries, petrochemicals, oil and gas, food processing, offshore drilling, power generation, and seawater equipment. Condensers, heat exchangers, chemical plants and pharmaceutical equipment all depend on them. Strict raw material inspection comes first, then forging or rolling, heat treatment for strength, drilling, and precise CNC machining. Smooth surfaces and precise dimensions are guaranteed by final finishing. Prior to delivery every flange is examined under stringent quality control.
