Inconel Pipe

Product Details:

Incoloy  800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H, and the addition of up to 1.20 percent aluminum and titanium in alloy 800HT. Incoloy 800 was the first of these alloys and it was slightly modified into Incoloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. Incoloy 800HT has further modifications to the combined titanium and aluminum levels (.85-1.20%) to ensure optimum high temperature properties. The nickel alloy is dual certified (800H/HT) and combines the properties of both forms. Incoloy 800H/HT alloy was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, alloys 800H and 800HT have superior creep and stress rupture properties.

Alloy 800HT (UNS N08811) Chemical Composition, %:

Product Details:

Inconel 601 is a solid solution nickel chromium alloy for high temperature heat resistance. It has excellent oxidation resistance. Inconel 601 also has good resistance to carburising but should not be used in atmospheres containing sulphur, particularly reducing sulphur. Inconel 601 has good resistance to nitriding in dissociated ammonia, and is only outperformed by Inconel 600 in this application. Inconel 601 has good strength, ductility and toughness, and can be used at cryogenic temperatures.

 

Typical Applications:

Thermal processing equipment – baskets, trays, fixtures, radiant tubes, muffles, retorts, flame shields, woven wire conveyers, burner nozzles and electrical resistance heating wires. Other applications include thermocouple protection tubes, process heaters, condenser tubes, catalyst supports in nitric acid manufacture, exhaust systems in gasoline engines and combustion chambers, superheater tube supports and ash handling in power generation.
