High temperature alloy GH1140 Description

The high temperature alloy GH1140 is a solid solution strengthened iron-nickel-based superalloy. 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 high temperature alloy GH1140 has medium thermal strength and high plasticity. .Good thermal fatigue, microstructure stability and welding process performance.
