Raw Material Selection: The production begins with selecting high-quality raw materials, including nickel, chromium, molybdenum, niobium, and other alloying elements in precise proportions. These materials are sourced from reputable suppliers to ensure consistency and purity.
Melting: The selected raw materials are melted together in a vacuum induction furnace or an electric arc furnace under controlled conditions to achieve the desired chemical composition. This process ensures homogeneity and removes any impurities that could affect the final properties of the alloy.
Casting: Once the alloy is molten and homogeneous, it is cast into ingots or continuous casting molds to form large semi-finished shapes. In some cases, the alloy may undergo secondary refining processes such as electroslag remelting (ESR) or vacuum arc remelting (VAR) to further improve its cleanliness and microstructure.
Hot Working: The cast ingots are then subjected to hot working processes such as forging or rolling at elevated temperatures. This helps shape the material into intermediate forms such as billets or bars while refining the microstructure and improving mechanical properties.
Annealing: After hot working, the intermediate forms may undergo annealing treatments to relieve internal stresses and improve machinability. Annealing involves heating the material to a specific temperature and holding it for a predetermined time before slowly cooling it down to room temperature.
Cold Drawing or Extrusion: The annealed material is then further processed through cold drawing or extrusion processes to reduce its diameter and achieve the desired dimensions for the rod. Cold working enhances the material's strength and surface finish while maintaining its corrosion resistance.
Finishing Operations: The cold-drawn or extruded rods may undergo additional finishing operations such as straightening, cutting, grinding, or polishing to meet the specified tolerances and surface requirements.
Quality Control: Throughout the production process, rigorous quality control measures are implemented to ensure that the finished rods meet the required specifications and standards for chemical composition, mechanical properties, dimensional accuracy, and surface finish.
Final Inspection and Packaging: Once the rods pass all quality checks, they undergo final inspection before being packaged and prepared for shipment to customers. Proper packaging is essential to protect the rods from damage during transportation and storage.
