ASTM B163 Incoloy 800HT UNS N08811 Bright Surface Nickel Alloy Pipes

ASTM B163 Incoloy 800HT UNS N08811 Bright Surface Nickel Alloy Pipes

Our Alloy 800HT/825 tube products can be offered in seamless, welded or welded and cold drawn form, depending on the alloy you require. Our Alloy 800HT/825 seamless and welded tubes size range starts at 1/2” NB or OD size and goes up to 6″ NB and OD.

We can offer Nickel Alloy 800HT/825 Tubing in random lengths of up to 6meters long or cut to a specific length as ordered. Incoloy pipes and tubes are largely used for piping process systems.

Incoloy 800, Incoloy 800H and 800HT, are all nickel-iron-chromium alloys, with similar basic composition. However, Incoloy 800 differs from the other two alloys, due to the higher level of carbon in alloy 800H, and the addition of up to 1.20% aluminum and titanium in alloy 800HT. The high nickel and chromium contents of Incoloy 800H, 800HT and 800 ensure excellent resistance to oxidation. Incoloy 800 is primarily used in applications with temperatures up to 1100° F, where alloys 800H and 800HT are normally used in temperatures above 1100° F where resistance to creep and rupture is required.

Incoloy 825 is a nickel-iron-chromium alloy, with addition of molybdenum and copper, exhibiting excellent corrosion resistance in both reducing and oxidizing media. Alloy 825 offers good mechanical properties at both room and elevated temperatures, up to approximately 550℃.

Alloy 800HT/825 seamless pipes and tubing’s are available in both OD and NB sizes. In addition to standard sizes, which are available in stock, our specialty is to manufacture and supply custom size Alloy 800HT/825 cold drawn seamless tubing’s from our factory.

Incoloy 800HT is known for many of the same outstanding characteristics as Incoloy 800H including:

• Excellent resistance to oxidation, sulfidation, and carburization.
• Higher creep and rupture properties for high temperature situations above 1100°F (600°C)
• Resistant to high temperature corrosion and prolonged exposure
• Readily machined by standard methods
• Resistance to aqueous corrosion at moderate temperatures

User of Incoloy 800HT and Nickel Alloy 800HT use the alloy for a wide range of high-temperature applications including:

• Hydrocarbon cracking
• Industrial furnace and boiler components and equipment
• Equipment for Heat-Treating
• Pressure vessels and heat exchangers
• Chemical and Petrochemical processing
