FAQ's
What makes Incoloy 800HT different from 800H and 800?
What makes Incoloy 800HT different from 800H and 800?
Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys that differ primarily in carbon (C), aluminum (Al), and titanium (Ti) content, and solution annealing temperature, which affects their high-temperature strength. Incoloy 800H has a controlled, higher carbon range (0.05–0.10%) than Incoloy 800 (0.10% max) and a coarser grain size, giving it improved creep and rupture strength above 1100°F (600°C). Incoloy 800HT is a further modification of 800H with a tighter control on the combined content of aluminum and titanium (0.85% to 1.20%), resulting in optimum high-temperature strength and even greater resistance to creep and stress rupture.
Why are Incoloy 800HT Seamless Tubes used in industrial furnaces?
Why are Incoloy 800HT Seamless Tubes used in industrial furnaces?
Incoloy 800HT Seamless Tubes are used in industrial furnaces because of their superior high-temperature performance. They offer excellent resistance to oxidation and carburization in high-temperature atmospheres, which is crucial in furnace environments.4 The controlled carbon and combined aluminum/titanium content provides high creep and stress rupture strength, ensuring the tubes maintain their structural integrity and long service life even with prolonged exposure to extreme heat and load above 1100°F (600°C).
What industries commonly use Incoloy 800HT Seamless Tubes?
What industries commonly use Incoloy 800HT Seamless Tubes?
Incoloy 800HT Seamless Tubes are primarily utilized in industries involving high temperatures and corrosive environments. Common industries include petrochemical and chemical processing (for heat exchangers, piping, and hydrocarbon cracking), power generation (for superheater and reheater tubing and headers), and thermal processing and heat-treating equipment (for furnace components like muffles and retorts). They are also used in nuclear power plants and for pressure vessels.
Can Thaida supply customized Incoloy 800HT Seamless Tubes?
Can Thaida supply customized Incoloy 800HT Seamless Tubes?
Yes, we supply customized Incoloy 800HT Seamless Tubes. Customization can involve supplying tubes in specific dimensions (Outer Diameter, Wall Thickness, and Length), different finishes (e.g., annealed and pickled, bright annealed), and specific test requirements, to meet the unique design and application needs of the customer.
What is incoloy 800HT material?
What is incoloy 800HT material?
Incoloy 800HT is a high-performance, iron-nickel-chromium alloy (often referred to as a superalloy) that is part of the 800 series. It is a solid solution strengthened material specifically designed for demanding, high-temperature structural applications where enhanced creep and stress rupture strength is required. Its unique chemical balance and solution heat treatment process provide excellent resistance to high-temperature corrosion, including oxidation, carburization, and nitriding, along with good general aqueous corrosion resistance.
What is the difference between incoloy 800 and 800H tube?
What is the difference between incoloy 800 and 800H tube?
The key difference between Incoloy 800 and Incoloy 800H tubes lies in their carbon content and grain size, which affects high-temperature mechanical properties. Incoloy 800H has a restricted, higher carbon range (0.05% to 0.10%) compared to Incoloy 800 (0.10% maximum) and is required to have a coarser grain size due to its higher minimum solution annealing temperature. These controls significantly enhance the creep and stress rupture properties of 800H, making it better suited for long-term service above 1100°F (600°C).
How to weld incoloy 800H tube?
How to weld incoloy 800H tube?
Incoloy 800H tubes can be welded using common techniques suitable for stainless steels, such as Gas Tungsten Arc Welding (GTAW/TIG), Shielded Metal Arc Welding (SMAW), or Gas Metal Arc Welding (GMAW/MIG). It’s crucial to use appropriate filler metals, such as AWS A5.14 ERNiCrMo-3 or ERNiFeCr-1, and maintain a low heat input to control the weld bead profile and avoid excessive softening of the base metal. The surface should be cleaned thoroughly, and for thick sections, proper preheating and post-weld heat treatment may be required, although post-weld heating is often not necessary for thin-walled tubes.
What is the composition of an incoloy 800H tube?
What is the composition of an incoloy 800H tube?
The core composition of an Incoloy 800H tube is an iron-nickel-chromium alloy.17 The main elements are Nickel (Ni) 30.0% to 35.0%, Chromium (Cr) 19.0% to 23.0%, and Iron (Fe) 39.5% minimum. It also contains specific ranges of Carbon (C) 0.05% to 0.10% and a controlled total of Aluminum + Titanium (Al+Ti) 0.30% to 1.20%. This precise balance of elements and the controlled carbon content contribute to its excellent high-temperature strength and corrosion resistance.
