Nickel Alloy Tubes 800H • UNS N08810 • 1.4958

Short Description:

800H (UNS N08810), 800HT (UNS N08811) are nickel-iron-chromium alloys that provide high strength and excellent resistance to oxidation and carburization at high temperatures. High creep strength is attained through control over crystal grains—via high temperature heat treatment, together with fine control over carbon, titanium, and aluminum content.
