allowing for ease of fabrication and customization to meet the precise needs of
aerospace and industrial applications.

Manufacturing Process of GH2747 Alloy Bars
The manufacturing process of GH2747, GH747, and Nimonic80A alloys involves
several stages to ensure the final product meets the rigorous demands of high-
temperature applications:

Melting: High-purity raw materials are melted in an electric arc or induction
furnace. The molten metal is refined to remove impurities and achieve the
desired chemical composition.

Casting: The alloy is cast into ingots. These ingots are then heat-treated to
homogenize the material and eliminate segregation.

Forging: The ingots are hot-forged at temperatures above 1100°C, which refines
the microstructure and improves the mechanical properties of the alloy.

Hot Rolling: After forging, the material is hot-rolled to reduce thickness and
achieve the required final dimensions.

Annealing: The rolled bars are annealed at temperatures between 900-950°C to
relieve internal stresses and improve ductility.

Finishing: The final step involves cutting the bars to the required lengths and
applying necessary surface treatments, such as grinding or polishing, to
protect the alloy from environmental factors.
