Heat exchangers made from Incoloy 825 UNS N08825 are widely used in the chemical processing industry, where they are used to handle highly corrosive environments, such as those found in sulfuric acid and hydrochloric acid production. In addition, Alloy 825 Heat Exchanger Tubes are also commonly used in the oil and gas industry, where they are used to handle corrosive and high-temperature fluids.
What is Heat Exchangers?
Heat exchangers are used to transfer heat from one medium to another, and are vital components in a wide range of industries, including petrochemicals, power generation, and the food and beverage industry. In order for a heat exchanger to function efficiently and reliably, it must be made from materials that are resistant to corrosion, heat, and pressure. One such material is 2.4858 Incoloy 825.
What is Incoloy 825 UNS N08825 Material?
2.4858 Incoloy 825 is a type of nickel-iron-chromium alloy that contains high levels of nickel, which gives it excellent resistance to corrosion and pitting. UNS N08825 material also contains molybdenum and copper, which help to increase its resistance to both reducing and oxidizing acids. In addition, it has good mechanical properties and is resistant to stress corrosion cracking.
