Alloy 800HT Round Steel Incoloy 800HT Nickel-Chromium-Iron Alloy W.Nr.1.4876 Round Bar.
Incoloy 800HT has a density of approximately 8.0g/cm³.
Incoloy 800HT is a nickel-iron-chromium alloy with high thermal stability and oxidation resistance for use in high temperature corrosive environments. It was originally designed to address corrosion issues in high temperature environments, especially in the petrochemical, power generation and heat treatment industries. The alloy has improved mechanical properties and oxidation resistance at high temperatures through strict carbon control and an enhanced heat treatment process. Incoloy 800HT exhibits excellent corrosion resistance in a variety of oxidizing and non-oxidizing environments, especially in water containing chlorides and low concentrations of NAOH, and has excellent resistance to stress corrosion. In addition, it is widely used in chemical heaters, furnace tubes, heat exchangers, nuclear reactors and other occasions where high temperature corrosion resistant materials are required.
Incoloy 800HT, also known as N08811, is a nickel-iron-chromium alloy with extremely high thermal stability. This alloy is an improvement of the Incoloy 800 series, through strict carbon control and enhanced heat treatment process to improve its mechanical properties and oxidation resistance at high temperatures. Its original design was mainly to deal with corrosion problems in high temperature environments, especially in the petrochemical, power generation and heat treatment industries...
