GH33Alloy properties：

HuaNickel GH33alloy has a greater tendency to form uneven grains and coarse grains during hot rolling and forging, which is easy to produce coarse-grained waste. In addition, the production process should be strictly controlled to avoid a decrease in tensile plasticity at 700°C.

GH33Uses of alloys：

HuaNickel GH33alloy has been used in the manufacture of aero engine turbine working blades, turbine disks and other high-temperature load-bearing parts.

GH33Process performance：

Welding process: GH33alloy can be argon arc welding in the solution state, and should be treated in time after welding to eliminate welding stress.
