    GH3030 features and applications overview:
    The early development of the alloy is solid solution strengthening of 80Ni-20Cr alloy high-temperature, chemical composition is simple, at 800 ℃ with the satisfaction of the following strength and high thermal plastic, and has good resistance to oxidation, thermal fatigue, cold stamping and welding performance. Alloy after solution treatment for single-phase austenite, the process of using organizational stability. 800 ℃ work mainly for the following turbine engine combustion chamber components and the following requirements at 1100 ℃ oxidation but the loads of other small high-temperature components.

GH3030 metallographic structure:
     The alloy after solution treatment at 1000 ℃ for single-phase austenite, a small amount between TiC and Ti (CN).
 
GH3030 process performance and requirements:
1, the alloy has a good performance can be forged, forging heating temperature of 1180 ℃, final forging 900 ℃.

2, the alloy grain size and average degree of deformation of the forging, final forging temperature.

3, heat treatment, parts surface oxide can be blown clean sand or pickling methods.
