Forging
Forging is a manufacturing process that involves shaping metal through the application of force.
What are Incoloy 800/800H/800HT forged fittings?
Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with varying levels of carbon,
aluminum, and titanium. These alloys offer excellent corrosion resistance, high-temperature
strength, and good creep and rupture properties. Forged fittings are components used in
piping systems to connect pipes, change direction, or control the flow of fluids. They are
created through a forging process, which involves shaping heated metal using localized
compressive forces.
What are the advantages of using Incoloy 800/800H/800HT forged
fittings?
Incoloy 800/800H/800HT forged fittings offer several advantages,
including:
• Excellent resistance to oxidation, carburization, and sulfidation at high
temperatures.
• Good strength and toughness at elevated temperatures.
• Outstanding corrosion resistance in various environments, such as acidic and
chloride-containing solutions.
• High resistance to stress corrosion cracking.
• Good fabrication and weldability.

What are the temperature limits for Incoloy 800/800H/800HT forged
fittings?
The temperature limits for Incoloy 800/800H/800HT forged
fittings depend on the specific alloy and application. In general,
these alloys can be used in temperatures ranging from cryogenic (-423°F/-253°C) up to around
1800°F (980°C).
What are the applications of Incoloy 800/800H/800HT forged fittings?
Incoloy 800/800H/800HT forged fittings find applications in various industries,
including:
• Petrochemical and chemical processing.
• Power generation.
• Heat treating equipment.
• Industrial furnaces.
• Gas turbines.
• Aerospace industry.
• Oil and gas production.
What are the differences between Incoloy 800, 800H, and 800HT?
• Incoloy 800: This alloy has a carbon content of 0.1% max and is commonly
used in applications involving exposure to sulfur compounds.
• Incoloy 800H: It has a higher carbon content (0.05-0.10%) than Incoloy
800, which offers improved creep and rupture strength.
• Incoloy 800HT: This alloy has an even higher carbon content (0.6-0.10%)
and is optimized for high-temperature applications, offering superior creep strength.
What is the difference between forged fittings and cast fittings?
Forged fittings are made by shaping metal through a forging process, which results in
improved mechanical properties and better grain structure. Cast fittings, on the other hand,
are made by pouring molten metal into a mold, which can result in lower strength and less
desirable grain structure compared to forged fittings.
