Incoloy 800HT alloy pipe,nickel alloy 800HT tube,nickel alloy tubing

Short Description:

Incoloy 800HT (UNS N08811 / W.Nr. 1.4959) nickel-iron-chromium alloys that have the same basic composition as INCOLOY alloy 800 but with significantly higher creep-rupture strength. The higher strength results from close control of the carbon, aluminum and titanium contents in conjunction with a high temperature anneal. Used in chemical and petrochemical processing, power plants for super-heater and reheater tubing, industrial furnaces and heat-treating equipment

Features

▪ Resistance to prolonged exposure to elevated temperatures
▪ Excellent resistance to oxidation, sulfidation, and carburization
▪ Added Carbon and annealing treatment allows for higher creep and rupture properties above 600℃
▪ Resistant to high temperature corrosion
▪ Readily machined by standard methods
▪ Best joined/welded using products for high temperature situations
▪ Resistance to aqueous corrosion at moderate temperatures

Application

▪ Chemical and Petrochemical Processing—process equipment for the production of ethylene, ethylene dichloride, acetic anhydride, ketene, nitric acid and oxy-alcohol
▪ Petroleum Refining—steam/hydrocarbon reformers and hydrodealkylation units
▪ Power Generation—steam super-heaters and high temperature heat exchangers in gas-cooled nuclear reactors, heat exchangers and piping systems in coal-fired power plants
▪ Thermal Processing Fixtures—radiant tubes, muffles, retorts and fixtures for heat-treating furnaces
