High Temperature Rod
Product Details
High-temperature alloys, including the GH2747, are specialized metals based on iron, nickel, and cobalt, designed to withstand prolonged exposure to temperatures above 600°C while maintaining structural integrity. These alloys are highly regarded for their excellent high-temperature strength, superior oxidation and corrosion resistance, and outstanding fatigue performance and fracture toughness. Their single-phase austenite structure provides excellent stability, even at elevated temperatures, making them ideal for demanding industrial applications.
GH2747, a nickel-based high-temperature alloy, is a key material in industries where extreme conditions are a daily requirement. With its ability to perform reliably in high-stress, high-temperature environments, this alloy is indispensable in the aerospace and power generation sectors, especially in the manufacturing of jet engines and industrial gas turbines.
Key Features of GH2747 High Temperature Alloy Bar
High Temperature Strength:
GH2747 exhibits exceptional strength at elevated temperatures, making it ideal for use in aerospace and turbine applications where parts must withstand high heat for prolonged periods.
Excellent Corrosion and Oxidation Resistance:
The alloy's composition ensures superior resistance to oxidation and corrosion, even in harsh, high-temperature environments, such as those found in jet engines and chemical processing plants.
Fatigue and Fracture Resistance:
GH2747’s fatigue resistance and fracture toughness are critical for components exposed to cyclic stresses, such as turbine blades and engine parts, ensuring long-lasting durability.
Versatile Applications:
This alloy is commonly used in manufacturing aerospace engine components, turbine blades, heat exchangers, and other high-performance applications where reliability under extreme conditions is essential.
Manufacturing Process
Melting
The process starts by melting high-purity raw materials in an electric arc or induction furnace. This ensures the production of a clean and consistent alloy with the desired chemical composition.
Casting
Once melted, the alloy is cast into ingots. These ingots undergo homogenization heat treatment to eliminate segregation and achieve uniformity in structure.
Forging
The ingots are then hot-forged at temperatures exceeding 1100°C. This step refines the microstructure, improving the mechanical properties and enhancing strength.
Hot Rolling
The forged material undergoes hot rolling to reduce its thickness and achieve the desired dimensions. The rolling process also improves the alloy’s directional properties.
Annealing
The rolled bars are annealed to relieve internal stresses, enhancing ductility and preparing the material for further machining.
Finishing
Finally, the bars are cut to the required length, and surface treatments, such as grinding, polishing, or coating, are applied to improve performance and protect against environmental factors.
