Nickel Alloy Steel Flange Incoloy 800HT is a high-performance, nickel-chromium-iron alloy designed for superior strength, oxidation resistance, and excellent performance in high-temperature environments. Incoloy 800HT flanges are specifically formulated to withstand extreme service conditions, offering unparalleled resistance to oxidation, carburization, and scaling in temperatures up to 1100°C (2012°F). This makes Incoloy 800HT an ideal choice for industries such as chemical processing, petrochemical, heat treatment, and power generation, where both high temperatures and aggressive chemicals are encountered.
Incoloy 800HT is engineered to maintain its mechanical integrity and resistance to corrosion even in the most demanding environments. The alloy’s high chromium content enhances its oxidation resistance, while its nickel content ensures it performs reliably under thermal cycling and high-pressure conditions. Additionally, the alloy’s excellent weldability and formability make it easy to incorporate into complex piping systems and industrial equipment.
Incoloy 800HT flanges are manufactured to the highest standards, including ASTM B564 and ASME SB564, ensuring superior quality and performance. This alloy offers exceptional creep and rupture strength, making it the preferred choice for high-temperature, high-pressure applications. The alloy's ability to resist oxidation and carburization is critical in industries where temperatures fluctuate dramatically, and corrosion resistance is essential.
Incoloy 800HT is widely used in the chemical processing, power generation, and petrochemical industries, where it provides long-term reliability in environments subjected to steam, gases, acids, and other corrosive media. Its excellent performance in applications involving both thermal stress and aggressive chemicals makes it an indispensable material for ensuring the efficiency and safety of industrial processes.
