incoloy B407 800HT pipes best quality

Alloy 800 – The 800 series of alloy (Incoloy 800, 800H and 800HT) are nickel-iron-chromium superalloys that have excellent properties of high temperature strength and resistance to oxidation, carburization and other types of high temperature corrosion. Alloy 800, 800H and 800HT are used in various applications from furnace components, petrochemical furnace cracker tubes to sheathing for electrical heating elements.

The creep and rupture strengths of Incoloy alloys 800H and 800HT are significantly higher than those of Incoloy 800. The chemical composition limits for these three alloys are nearly identical. However, chemical composition limits vary for carbon, aluminum, and titanium. This nickel alloy resists the formation of grain boundary deposits in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded state. UNS N08800, UNS N08810 and UNS N08811 seamless pipes are all nickel-iron-chromium alloys with similar basic compositions. However, Incoloy 800 differs from the other two alloys because of the higher carbon content in Incoloy 800H and the addition of up to 1.20% aluminum and titanium in alloy 800HT.

 

Incoloy 800HT pipes are made from alloy 800ht that has excellent resistance to oxidation and corrosion, they are used in a wide range of high-temperature applications, including chemical processing, nuclear power plants, heat exchangers, furnace components, and more.

Incoloy 800HT pipes also have excellent resistance to aqueous corrosion, stress corrosion cracking, and intergranular corrosion. They are also resistant to sulfur-containing atmospheres and have good mechanical properties at high temperatures.
