ASTM B564 UNS N08811 Incoloy 800HT Flange is a high-quality flange that is designed to maintain excellent strength and corrosion resistance at elevated temperatures. The material used to manufacture this flange is a nickel-iron-chromium alloy with added titanium, aluminum, and carbon.
HT PIPE provides all kinds of flanges: Incoloy 800HT WN Flange, 800HT SW Flange, UNS N08811 threaded Flange, Incoloy 800HT blind Flange, Incoloy 800HT SO Flange, ect.
They are widely used in various industries, including chemical processing, power generation, oil and gas, and heat treating industries.
The ASTM B564 UNS N08811 Incoloy 800HT Flange has a range of features that make it stand out. For instance, it has excellent oxidation resistance in high-temperature environments. The alloy also resists carburization, nitriding, and other forms of high-temperature corrosion.
