Inconel Alloy 783, which is popular by the names Inconel 783 or Inconel 783, is a nickel-chromium-iron alloy that has a great strength and outstanding oxidation resistance. Generally it possesses excellent creep resistance and is perfectly deployed in the hot chamber of the combustors for the compressor seals and turbine rotors components in the gas turbines. This chemical composition is a combination of nickel, chromium, iron and other type of elements that guarantee the best performance in harsh environments. Inconel 783, a nickel-based alloy, is known as a superalloy because it retains top mechanical properties at elevated temperatures, the reason why it is often used in aerospace and industrial applications. It has a range of chemical properties that guarantee resistance to corrosion, oxidation and thermal fatigue. Thorough and understandable grade charts, tables and pdf files are provided on our company website, giving a person detailed information about its chemical composition, properties, and applications.
Inconel Alloy 783 is a nickel-chromium-iron alloy with good corrosion resistance and high temperature resistance with components of aluminum, titanium and niobium. Its chemical composition is responsible for its exceptional strength and the resistance of oxidation that occurs at high temperatures and therefore, it is ideal for applications in gas turbine components, like combustors liners and transition ducts. As its unique combination of elements, Inconel Alloy 783 has the superior mechanical properties and is creep and fatigue resistant and can therefore be used in aerospace and industrial applications with the demanding requirements.
