Incoloy 800 and Incoloy 825 Flanges are specialized components made from two different nickel-iron-chromium alloys, each designed to offer unique features and capabilities for various industrial applications.

Incoloy 800 Flanges are fabricated from the alloy Incoloy 800, which is known for its excellent high-temperature strength and resistance to oxidation and carburization. The flanges' outstanding mechanical properties make them ideal for use in applications where they are exposed to elevated temperatures, such as in heat exchangers, furnace components, and petrochemical processing equipment. Incoloy 800 boasts a chemical composition containing approximately 32% nickel, 21% chromium, 46% iron, and small amounts of aluminum, titanium, and carbon. This composition contributes to the alloy's remarkable corrosion resistance in a variety of environments, including sulfur-containing atmospheres, and its ability to retain strength even in high-temperature conditions. Heat treatment for Incoloy 800 Flanges involves annealing at temperatures between 1800°F to 2000°F (980°C to 1095°C), followed by rapid cooling to achieve the desired properties.

Incoloy 825 Flanges, on the other hand, are made from the alloy Incoloy 825, which is designed to provide exceptional corrosion resistance in various corrosive environments, particularly those containing sulfuric acid, phosphoric acid, and seawater. These flanges are often employed in chemical processing, petrochemical, and marine industries, where they offer superior resistance to both reducing and oxidizing conditions. Incoloy 825 typically consists of approximately 42% nickel, 21.5% chromium, 30% iron, with additions of molybdenum, copper, and titanium. The precise chemical composition of Incoloy 825 contributes to its ability to resist corrosion in aggressive environments. Heat treatment for Incoloy 825 Flanges involves annealing at temperatures between 1600°F to 1800°F (870°C to 980°C), followed by rapid cooling to achieve the desired mechanical properties.

 Inconel 800 Flanges

Both Incoloy 800 and Incoloy 825 Flanges are highly versatile and find application in a wide range of industries. Incoloy 800 Flanges are commonly used in heat-treating equipment, petrochemical plants, and power generation facilities, where their high-temperature strength and oxidation resistance are crucial for maintaining operational integrity. In contrast, Incoloy 825 Flanges are extensively used in chemical processing, particularly in handling sulfuric and phosphoric acids, as well as in marine environments where they demonstrate excellent resistance to seawater and corrosive chloride compounds. Their reliability and corrosion-resistant properties make both types of flanges essential components for critical applications, ensuring the durability and longevity of equipment operating in challenging conditions.
