Technology
The manufacturing technology for 2205 duplex stainless steel sheets typically involves several processes to transform raw materials into the final product. Here is an overview of the typical manufacturing process:
- Melting and Casting: The process begins with melting the raw materials in an electric arc furnace or an induction furnace. The raw materials usually include iron, chromium, nickel, molybdenum, and other alloying elements required to achieve the desired composition of 2205 duplex stainless steel. The molten metal is then cast into large ingots or billets.
- Hot Rolling: The cast ingots or billets are heated and passed through a series of rolling mills to reduce the thickness and shape them into long, flat sheets. The hot rolling process helps to refine the grain structure and improve the mechanical properties of the stainless steel.
- Annealing and Descaling: After hot rolling, the stainless steel sheets undergo an annealing process. Annealing involves heating the sheets to a specific temperature and holding them at that temperature for a period of time, followed by controlled cooling. This process helps to relieve internal stresses and further refine the microstructure of the stainless steel. Descaling may also be performed during this stage to remove any scale or oxide layers from the surface.
- Cold Rolling: The annealed and descaled stainless steel sheets are then cold rolled to achieve the desired thickness, smoothness, and dimensional accuracy. Cold rolling involves passing the sheets through a series of rolling mills at room temperature, gradually reducing the thickness while imparting a smooth surface finish.
- Pickling and Passivation: The cold-rolled stainless steel sheets are subjected to a pickling process to remove any scale, oxide layers, or other impurities from the surface. Pickling is usually done using an acid solution that dissolves the surface impurities, leaving behind a clean and smooth surface. Passivation may also be performed to enhance the corrosion resistance of the stainless steel by forming a protective oxide layer on the surface.
- Cutting and Slitting: The pickled and passivated stainless steel sheets are cut into desired sizes using shearing or guillotine cutting machines. Slitting machines can also be used to slit the sheets into narrower strips, if required for specific applications.
- Surface Finishing: The surface of the stainless steel sheets undergoes various finishing processes to achieve the desired surface quality. This may include processes such as grinding, polishing, or brushing to remove any surface defects, improve the smoothness, and enhance the aesthetic appearance of the sheets.
- Quality Control: Throughout the manufacturing process, the stainless steel sheets undergo rigorous quality control inspections. This includes checking for dimensional accuracy, surface defects, mechanical properties, and chemical composition to ensure they meet the required specifications and standards.
- Packaging and Delivery: Once the stainless steel sheets pass quality control, they are typically packaged and prepared for delivery. They may be packed in protective materials such as plastic or paper to prevent damage during transportation.

Package
Packaging for stainless steel sheets must be designed to protect the product from physical damage, dust, and moisture during storage and transportation. It varies among manufacturers and is usually tailored to fit the size and quantity of the sheets and the specific requirements of the customer. Here’s a general overview of the packaging process:
- Surface Protection: The stainless steel sheets are typically protected with a removable plastic film, which provides a barrier against scratches and other surface damages.
- Bundling: The sheets are often stacked and then bundled together. This can be done with narrow strips of metal, plastic straps, or heavy-duty tape. The number of sheets per bundle can vary depending on the size of the sheets and the requirements of the customer.
