Remember that Alloy 800/ 800H/800HT®’s properties make them suitable for environments where resistance to oxidation, carburization, and other types of elevated temperature corrosion is required.
Alloy 800 - The 800 series of alloy (Incoloy 800, 800H and 800HT) are nickel-iron-chromium superalloys that have excellent properties of high temperature strength and resistance to oxidation, carburization and other types of high temperature corrosion. Alloy 800, 800H and 800HT are used in various applications from furnace components, petrochemical furnace cracker tubes to sheathing for electrical heating elements.
Incoloy 800 Pipe is one of the widely used pipes in the production of high strength equipment. The material has higher resistance against carburization and oxidation. This makes the material special for applications that require the carburization resistant and corrosion resistant properties. Alloy 800H Seamless Pipe is cold drawn and has high creep resistance and rupture resistance as well. The material is made ductile by the addition of nickel in the composition at the same time it is pretty much corrosion resistant because of the addition of chromium into the composition. The Ni 800 HT Hot Finished Pipe remains austenitic because of the nickel component. The high temperature resistance of the ASTM B407 UNS N08811 Incoloy 800HT Pipe makes it applicable in heat treating equipment and fixtures. The Incoloy 800 Seamless Pipe has higher precision in its dimensions.
This nature is important for narrow fixtures that require high precision. Application of Alloy 800 Pipe is seen in steam generator tubes, sheathing of electric heating elements, paper and pulp industries and in the petroleum processing plants. The most used shape is the Incoloy Alloy 800 Round Pipe whereas the other shapes are used as well. Depending on the application requirement, there could be other shapes such as the 800H Incoloy Square Pipe. Square pipes are usually used for applications that require structural strength. The Incoloy Alloy 800HT Clad Pipe is used for cladding of other material pipes. Since the material can withstand high temperatures, it could be used to prevent exposure of other softer material to heat. The Incoloy 800HT Pipe is used especially in the chemical and petrochemical processing, with the process equipment in ethylene and variations. The Incoloy 800H Pipe could be used interchangeably and these are both solution annealed. They have high creep resistance and rupture resistance as a result.
