Synergy Engineering Solution is a trusted manufacturer, stockist, and exporter of UNS N08800 Inconel 800 Plate Flanges, serving clients globally including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada, and across various regions in Africa. The company is known for delivering premium-quality flanges that comply with international standards and meet the stringent requirements of critical industrial applications.
Inconel 800 is a nickel-iron-chromium alloy that combines high strength with excellent resistance to oxidation and corrosion in high-temperature environments. UNS N08800 plate flanges are ideal for applications where thermal stability, mechanical strength, and resistance to scaling and carburization are essential. These flanges are widely used in industries such as chemical processing, petrochemical, power generation, and marine engineering.
Synergy Engineering Solution offers a full range of Inconel 800 flanges including blind, slip-on, socket weld, threaded, and lap joint flanges in various sizes and thicknesses. Each flange is manufactured under rigorous quality control measures to ensure precision, uniformity, and compliance with ASTM B564 and ASME SB564 standards, making them highly reliable for demanding applications.
The chemical composition of Inconel 800 generally includes 30–35% nickel, 19–23% chromium, 0.15–0.6% carbon, and minor amounts of manganese, silicon, and iron, providing a unique balance of corrosion resistance and high-temperature strength. This composition allows UNS N08800 flanges to resist oxidation, pitting, and intergranular corrosion in environments ranging from ambient to high temperatures.
Mechanically, Inconel 800 plate flanges exhibit tensile strength of 550–700 MPa, yield strength of 275–350 MPa, elongation of 40–50%, and excellent creep and thermal fatigue resistance, making them suitable for components exposed to thermal cycling, high pressures, and corrosive media. They are commonly employed in heat exchangers, furnace components, piping systems, and boiler applications.
