Incoloy 800 / 800H / 800HT Flanges Manufacturer

Incoloy 800 flanges are fittings that provide an easy and secure way to connect piping and other components. Incoloy N08800 Flanges are made using Incoloy 800 alloy, a nickel-iron-chromium alloy with excellent strength, corrosion resistance & high-temperature performance. Incoloy 800 flanges come in various types, such as slip-on, weld neck, threaded, blind, and lap joint flanges.

Incoloy 800 Flanges offers corrosion resistance and moderate high-temperature strength. Incoloy 800H has higher carbon content for improved high-temperature strength and creep resistance. Inconel 800HT Flanges further enhances these traits for extremely high-temperature applications.

One of the most significant benefits of Incoloy 800 Flanges is their high-temperature performance. Incoloy 800 alloy can withstand high temperatures up to 1100°C, making it ideal for high-temperature applications. Another benefit of Inconel Alloy 800 Pipe Flanges is their excellent resistance to oxidation & corrosion, which makes them suitable for applications in harsh environments. Nickel Alloy 800 Flanges are also easily machinable & have good flexibility & toughness, making them easy to work with.

ASTM B564 800H Flanges are used in various industrial applications, such as power generation, chemical processing, oil and gas, refineries, and aerospace. Incoloy 800 flanges are used in gas turbines, heat exchangers, and boilers in power generation. Incoloy 800 flanges are used in reactors, distillation columns, and piping systems in the chemical processing industry. In refineries and oil and gas applications, UNS N08810 Flanges are used in heat exchangers, piping & pressure vessels. In aerospace applications, Incoloy 800 flanges are used in jet engines and exhaust systems. The high-quality incoloy products we provide at Global Steel include Inconel 718 Flanges, Incoloy 825 Flanges and more.

Incoloy 1.4958 Forged Flanges have excellent mechanical properties, such as high strength, flexibility, and toughness. They also possess excellent resistance to oxidation, corrosion, and sulfidation. Incoloy 800 Industrial Flanges have good creep & stress-rupture strength at high temperatures. Incoloy 800 flanges can withstand high-temperature applications without losing their mechanical & physical properties. We provide an extensive range of products, such as Monel 400 Flanges, Nickel Alloy 201 Forged Fittings and more.

What is Incoloy 800 Flanges used for?

Incoloy 800 flanges are used in high-temperature applications where their excellent strength and corrosion resistance make them an ideal choice. They are commonly used in the petrochemical, chemical processing, and power generation industries. They are known for their ability to withstand high temperatures and pressures in furnace components, heat exchangers, and other high-temperature applications where resistance to oxidation and carburization is critical. Their excellent high-temperature strength and durability make them well-suited for use in harsh environments.

What material is equivalent to 800HT Flanges?

Incoloy 800HT flanges are made from a modified version of Incoloy 800 alloy which is designed to offer superior high-temperature strength and resistance to creep deformation. In terms of equivalent materials, Incoloy 800HT is very similar to Inconel 718, which is another high-strength nickel-based alloy. However, it is essential to note that these two alloys share some similarities in their composition and properties. However, they are not exact equivalents and may have different performance characteristics in certain applications.

What is the Incoloy 800H Flanges microstructure?

Incoloy 800H flanges have a microstructure that consists of a face-centered cubic (FCC) crystal lattice structure. These alloy primarily comprises nickel and chromium, with small amounts of iron, copper, and other elements. Incoloy 800H is a solid-solution-strengthened alloy that is strengthened by forming intermetallic precipitates. It also has excellent high-temperature strength and good resistance to oxidation, carburization, and nitridation. The microstructure and composition make it well-suited for high-temperature applications where resistance to thermal stress and creep deformation is critical.
