The GH4090 heat-resistant alloy round bar is produced through a rigorous and precise manufacturing process to ensure top-notch performance in high-stress applications. The key stages include:
Melting and Alloying: High-purity raw materials are melted in an electric arc furnace or vacuum induction furnace. The alloying elements, including nickel, chromium, and molybdenum, are added to achieve the desired chemical composition for heat resistance and mechanical strength.
Casting: After melting, the alloy is cast into ingots or billets. The cast material is then heat-treated to ensure uniform composition and eliminate segregation.
Forging: The ingots are heated to high temperatures and hot-forged to shape the alloy into round bars. This step enhances the grain structure and refines the mechanical properties, ensuring strength and durability.
Hot Rolling: The forged material undergoes hot rolling to achieve the final bar dimensions. The process improves the directional properties of the alloy, which is crucial for enhancing its fatigue resistance and strength.
Annealing: The rolled bars are annealed at a controlled temperature range to relieve internal stresses and optimize the alloy’s ductility and workability for machining and final use.
Finishing: The final step includes cutting the bars to the required lengths, followed by surface treatments like polishing or coating to protect against oxidation and environmental factors.
