Chemical Composition: Conforms to specified compositions of nickel, chromium, iron, and other alloying elements as per industry standards.
Applications: Widely used in high-temperature and corrosive environments, including applications in the chemical processing, aerospace, and nuclear industries.
In summary, Inconel 690 rods are versatile materials known for their exceptional performance in demanding conditions, making them suitable for a wide range of industrial applications. For specific product details and availability, it's best to consult with manufacturers or suppliers directly.
Chemical Composition: Inconel 690 primarily consists of nickel (Ni), chromium (Cr), and iron (Fe), with small additions of other elements such as molybdenum (Mo) and niobium (Nb). The exact composition may vary slightly depending on the specific grade and manufacturer.
High Temperature Resistance: Inconel 690 exhibits remarkable resistance to high temperatures, making it suitable for applications where exposure to heat is a concern. It retains its mechanical strength and structural integrity even at temperatures exceeding 1000°C (1832°F).
Corrosion Resistance: One of the most notable properties of Inconel 690 is its exceptional resistance to corrosion in a wide range of environments, including sulfur-containing atmospheres, solutions, and alkaline media. This corrosion resistance makes it ideal for use in chemical processing, petrochemical, and pollution control industries.
Oxidation Resistance: Inconel 690 demonstrates excellent resistance to oxidation, even in environments with high levels of oxygen and sulfur. This property allows it to maintain its surface integrity and prevent the formation of oxide scales, which can compromise the performance of other materials at elevated temperatures.
Creep and Rupture Strength: The alloy's superior creep and rupture strength make it suitable for applications subjected to prolonged exposure to high temperatures and mechanical stress, such as furnace components, heat exchangers, and thermocouple sheaths.
Thermal Stability: Inconel 690 exhibits good thermal stability, retaining its properties over extended periods of operation at elevated temperatures. This stability minimizes the risk of degradation or failure, ensuring reliable performance in demanding environments.
Fabrication and Machinability: While machining Inconel 690 can be challenging due to its high strength and hardness, it is still readily fabricated using conventional methods such as forging, machining, and welding. However, specialized equipment and techniques may be required to achieve optimal results.

Raw Material Preparation: The process begins with sourcing high-quality raw materials, primarily nickel, chromium, and other alloying elements like iron, molybdenum, and titanium. These materials are carefully selected to meet the desired chemical composition and quality standards.
Melting: The raw materials are melted together in a controlled environment, often in an electric arc furnace or vacuum induction furnace. The melting process ensures thorough mixing and homogenization of the alloying elements to achieve the desired chemical composition.
Casting or Forming: Once the alloy is molten and properly mixed, it is cast into an initial form. For rod production, this typically involves continuous casting or pouring the molten metal into molds to form billets or ingots of the desired size and shape.
Hot Working: The cast billets or ingots are then subjected to hot working processes such as rolling or extrusion. During hot working, the material is deformed at elevated temperatures to reduce its cross-section and elongate it into the desired rod shape. This process helps refine the microstructure of the alloy and improve its mechanical properties.
Cold Working (Optional): Depending on the desired properties and dimensions, the hot-worked rods may undergo additional cold working processes such as drawing or cold rolling. Cold working further refines the microstructure, increases the strength, and achieves the desired dimensions with tight tolerances.
Heat Treatment: After forming and shaping, the Inconel 690 rods may undergo heat treatment to optimize their mechanical properties and enhance their performance at high temperatures. Heat treatment processes may include annealing, solution annealing, or aging treatments, depending on the specific requirements of the application.
Surface Finishing: Once the rods have been formed and heat-treated, they undergo surface finishing processes to achieve the desired surface quality and appearance. This may include polishing, grinding, or chemical treatments to remove surface defects and improve surface finish.
Quality Control: Throughout the production process, rigorous quality control measures are implemented to ensure that the Inconel 690 rods meet the specified dimensional, mechanical, and chemical requirements. This includes inspections, testing, and certifications to verify compliance with industry standards and customer specifications.
Packaging and Shipping: Finally, the finished rods are carefully packaged to protect them during transportation and storage. They are then shipped to customers or distributors for further processing or direct use in various industrial applications.
