Incoloy 801 & 802

Incoloy 801: UNS Designation N08801, also known as “Alloy 801”; Incoloy 802: UNS Designation N08802, “Alloy 802”. Very similar to Incoloy 800, both Incoloy 801 and Incoloy 802 are iron-nickel-chromium alloys. Incoloy 801 has increased titanium additions raising the tensile and rupture strength dramatically and it has exceptional resistance to polythionic acid cracking. Incoloy 802 offers competitive high-temperature strength capabilities because of its high carbon level and has been used extensively in sinter deck plate applications for handling abrasive, high-temperature environments. Metals-Piping mainly supplies Incoloy 801 & 802 in the form of wire.
