GH35 superalloy rod is a Fe-Ni-Cr-based solid solution strengthened deformed superalloy, which is solid solution strengthened with elements such as chromium and tungsten, and the operating temperature is below 900 °C.
The alloy has high thermal strength, and the level is close to that of GH3039 nickel-based alloy.
The alloy has good hot working plasticity and welding and cold forming process performance.
The main products are plates, bars, wires and rings.
