GH2302 is a Fe-Ni-Cr-based precipitation hardening deformation high-temperature alloy. The alloy can be used for a long time under 700ºC and for short time at 850ºC. The structure and properties of the alloy are stable, and it has good cold and hot forming properties. The main products are bars and plates.
