Incoloy 800 800H 800HT Nickel Alloy Wire High Temperature Oxidation Resistant for Industrial Furnace
Incoloy 800 Series Nickel Alloy Wire (800 / 800H / 800HT)
Our Incoloy 800 series nickel alloy wire covers three grades: Incoloy 800 (UNS N08800 / W.Nr. 1.4876), Incoloy 800H (UNS N08810 / W.Nr. 1.4958), and Incoloy 800HT (UNS N08811 / W.Nr. 1.4959). Each grade is a nickel-iron-chromium alloy engineered for outstanding high-temperature strength and environmental resistance.
