High-Temperature Resistance: GH3039 alloy excels in high-temperature environments, ensuring long-term performance in heat-intensive applications like gas turbines and steam boilers.
Creep Resistance: The alloy exhibits excellent resistance to deformation under stress at elevated temperatures, which is essential in power generation and aerospace industries.
Corrosion Resistance: Provides exceptional resistance to both high-temperature oxidation and acidic corrosion, making it ideal for gas turbines, power plants, and marine environments.
Seamless Design: Manufactured as seamless tubes, ensuring uniformity and strength, and eliminating the risk of weld-related issues in critical applications.
High Durability: Offers excellent resistance to wear and high-temperature oxidation, significantly extending the service life of components in harsh conditions.
Power Generation:
In coal-fired power plants and gas-fired power generation, GH3039 tubes are used in critical components like superheaters, re-superheaters, and boiler tubes. Their resistance to high-temperature oxidation and creep makes them ideal for ultra-supercritical boilers.
Aerospace:
In gas turbines, GH3039 tubes are essential for turbine blades and guide vanes due to their outstanding high-temperature corrosion resistance. They ensure optimal performance and structural integrity at extreme temperatures and pressures.
Nuclear Power:
Steam generator heat transfer tubes require high-temperature alloys like GH3039 for their excellent solution corrosion resistance. These alloys help in maintaining efficiency and safety in nuclear power plants.
Petrochemical Industry:
GH3039 high-temperature tubes are widely used in oil and gas extraction, especially in deep-well drilling tools, where materials are exposed to CO2, H2S, and other corrosive environments at temperatures ranging from 4-150°C.
Coal Gasification:
The alloy’s ability to resist thermal corrosion and abrasion under high temperatures makes it ideal for coal gasification processes, contributing to energy conservation and emission reduction efforts.
Process
Melting:
High-purity raw materials are melted in an electric arc furnace or induction furnace. The metal is then refined to remove impurities and achieve the desired chemical composition.
Casting:
After refining, the alloy is cast into ingots and subjected to homogenization heat treatment to enhance uniformity and eliminate segregation.
Forging:
The ingots are hot-forged at temperatures above 1100°C to shape them and refine the microstructure, enhancing the mechanical properties of the alloy.
Hot Rolling:
After forging, the material undergoes hot rolling to reduce its thickness and achieve the final dimensions. This process also improves the directional properties of the alloy.
Annealing:
The rolled tubes are annealed at temperatures between 900-950°C to relieve internal stresses, increase ductility, and prepare the alloy for final machining.
Finishing:
The final step includes cutting the tubes to the required lengths and applying surface treatments, such as grinding, polishing, or coating, to ensure durability and protection against environmental factors.
Outstanding High-Temperature Performance: GH3039 tubes maintain their strength and integrity in extreme heat, making them ideal for high-temperature industrial applications.
Superior Corrosion Resistance: The material’s ability to resist oxidation and corrosion significantly enhances its performance in harsh environments, including power plants and petrochemical industries.
Seamless Design for Enhanced Strength: The seamless construction reduces potential points of failure and enhances the durability of the tubes under high stress and temperature.
Customizable Specifications: We offer flexible customization options, including custom sizes, lengths, and finishes to meet specific project requirements.
Longer Service Life: High resistance to wear and thermal corrosion ensures that the tubes have a longer lifespan in demanding environments, reducing maintenance costs and improving efficiency.
