Inconel alloy Inconel 686 is a high temperature corrosion resistant alloy
Inconel 686 Inconel alloy has excellent corrosion resistance and mechanical properties. It is used to manufacture oil and natural gas extraction and processing equipment, such as offshore oil well platforms, heat exchangers and reactors in petrochemical plants, as well as pipes and valves that require high durability and corrosion resistance.
Inconel 686 is widely used in the chemical industry to manufacture corrosion-resistant reactors, distillation columns, storage tanks, pipes, valves and other equipment. Due to its excellent corrosion resistance, it is particularly suitable for handling chemicals in strong acids, strong alkali and high temperature and high pressure environments.
Inconel 686 is used to manufacture key components such as seawater treatment systems, refrigeration systems and marine engine exhaust systems for ships to cope with the challenges of corrosion in seawater and high temperature and pressure.
Inconel 686 is used in the energy industry to manufacture equipment such as gas turbine generator components, burners and cogeneration systems to cope with the effects of high temperatures, pressures and corrosive gases.
Inconel 686 is used in key components such as nuclear reactor systems, nuclear fuel processing equipment and radiation protection materials in nuclear power plants. Its corrosion resistance and high temperature stability are of great significance in the nuclear industry.
Inconel 686 alloy processing technology:
1. Heat treatment: Inconel 686 usually requires heat treatment before processing to adjust its microstructure and improve the corrosion resistance of the material. Common heat treatment processes include solution annealing and solution overtime treatment.
2. Forging: Inconel 686 can be hot forged to improve the density and mechanical properties of the material. During the forging process, it is heated to the appropriate temperature and then deformed by pressure. The forging process helps increase the material's tensile strength and ductility.
3. Hot rolling and cold pressing: Inconel 686 can also be plastically deformed through hot rolling and cold pressing processes. Hot rolling refers to the deformation of materials by rolling at high temperatures, while cold pressing is pressure deformation at room temperature. These processes can be used to manufacture workpieces such as plates, sheets, rods and wires.
4. Machining: Inconel 686 has high strength and hardness, so machining may require the use of carbide tools and appropriate cutting parameters. Common machining processes include turning, milling, drilling and cutting.
5. **Welding**: Inconel 686 can be joined by a variety of welding methods, such as argon arc welding, TIG welding, MIG/MAG welding, electroslag welding, and plasma arc welding. Proper preheating and post-weld heat treatment are required before welding to ensure the strength and corrosion resistance of the weld.
