Explain |
GH1140 is an iron-nickel base superalloy with solid solution strengthening. In addition to containing a large amount of chromium, a small amount of tungsten, molybdenum, aluminum and titanium are used to strengthen the solid solution. The alloy has medium thermal strength, high plasticity, good thermal fatigue, structural stability and welding process performance. It is suitable for manufacturing plate structural parts and other high-temperature components of aero-engine and gas turbine combustor with working temperature below 850 ℃. |
