GH1140 iron based superalloy is a commonly used metal material with good High temperature strength, corrosion resistance and oxidation resistance. It is a solid solution reinforced alloy, by adding chromium, nickel and other elements to strengthen, can maintain excellent mechanical properties in high temperature environment. GH1140 alloy is widely used in aviation, aerospace, energy and other fields as a material for the manufacture of high-temperature components.
The chemical composition of GH1140 alloy mainly includes chromium, nickel, iron and other elements. Specifically, the content of chromium is 19.0-23.0%, the content of nickel is 3.5-5.5%, and the content of iron is a surplus. In addition, the alloy also contains a certain amount of titanium, aluminum and other elements as a strengthening phase.
GH1140 alloy has good process properties and can be processed both hot and cold. In terms of hot working, the alloy has good plasticity and can withstand various hot working processes, such as casting, forging, welding and so on. In the cold processing, the alloy can be rolled, drawn, stamping and other processing, to obtain a variety of shapes and specifications of products.
Because GH1140 alloy has excellent high temperature performance and corrosion resistance, it is widely used in aviation, aerospace, energy and other fields. In the aviation sector, the alloy can be used to manufacture high-temperature components of aircraft engines, such as combustion chambers, turbine blades, etc. In the aerospace field, the alloy can be used to manufacture high-temperature components of rocket engines, such as nozzles, combustion chambers, etc. In the energy sector, the alloy can be used to manufacture components in high-temperature reactors, such as fuel rods, control rods, etc.
