GH4199 is a Ni-Cr-based precipitation hardening deformation high-temperature alloy, the service temperature is below 950 degrees Celsius. Tungsten, molybdenum and chromium are added to the alloy for solid solution strengthening, aluminum and titanium are added to form an aging strengthening phase, and boron and magnesium are added to purify and strengthen the grain boundaries. The alloy has high strength, good oxidation resistance and good welding performance. Alloy is a kind of high temperature used in precipitation hardening plate.
