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 customized Alloy 800HT/825 cold drawn seamless tubing’s from our factory.
