Incoloy Alloy 800HT Sheet, is a nickel-iron-chromium alloy with excellent high temperature stability. With an operating temperature range up to 1100°C (2010°F), N08811 material is ideal for high temperature processes. With excellent corrosion resistance, Incoloy 800ht is particularly suitable for use in hazardous environments such as hydrogen sulfide and chlorides. 1.4549/1.4876 material also has good thermal expansion properties and high creep rupture strength, which helps avoid cracks caused by thermal stress. Easy to process and fabricate, our alloy 800HT supplier also offers tubes, bars, fittings, flanges, forgings, and wire.
