GH4099 is a Ni-Cr-based precipitation-hardening deformation high-temperature alloy that can be used long-term below 900℃, with a maximum short-term service temperature reaching 1000℃. The alloy incorporates chromium, cobalt, tungsten, and molybdenum for solid solution strengthening, while aluminum and titanium form aging-enhancing phases. Boron, cerium, and magnesium purify and strengthen grain boundaries. It exhibits high thermal strength, stable microstructure, and satisfactory cold/hot working and welding properties. Suitable for manufacturing high-temperature welded structural components such as aviation engine combustor chambers and afterburner chambers. Main products include hot-rolled bars, plates, wires, and forgings.
The density of GH4099 is ρ=8.47g/cm³.
