High Temperature Alloy Bar GH3030 GH30 Nimonic75 Rod For Aero Engine Combustion Chamber

High Temperature Alloy Bar 

GH3030 is an austenitic nickel-chromium alloy with a composition that includes approximately 20-23% chromium, 0.15% carbon, and trace amounts of manganese, silicon, and phosphorus. The balance is nickel. This specific composition endows GH3030 with excellent thermal stability, high creep resistance, and good weldability, making it suitable for use in environments up to 1000°C.GH3030 is an austenitic nickel-chromium alloy with a composition that includes approximately 20-23% chromium, 0.15% carbon, and trace amounts of manganese, silicon, and phosphorus.

Manufacturing Process

1. Melting

The process begins with the melting of high-purity raw materials in an electric arc furnace or induction furnace. The molten metal is then refined to remove impurities and achieve the desired chemical composition.

2. Casting

After refining, the alloy is cast into ingots. These ingots are typically subjected to a homogenization heat treatment to eliminate segregation and enhance uniformity.

3. Forging

The ingots are then hot-forged at temperatures above 1100°C to achieve the desired shape and grain structure. This step is crucial as it refines the microstructure and improves the mechanical properties of the alloy.

4. Hot Rolling

Following forging, the material undergoes hot rolling to reduce the thickness and achieve the final dimensions of the bars. This process also enhances the directional properties of the alloy.

5. Annealing

To relieve internal stresses and improve ductility, the rolled bars are annealed at temperatures around 900-950°C. This step ensures the material is ready for final machining and use.

6. Finishing

The final step involves cutting the bars to the required lengths and applying any necessary surface treatments. This may include grinding, polishing, or coating to protect against environmental factors
