Stainless steel coil has various applications in different industries including:
1. Construction: Stainless steel coil is used in construction to make roofing, cladding, and facades for buildings. It is also used for reinforcing bars, structural components, and bridges.
2. Automotive: Stainless steel coil is used in the production of exhaust systems, mufflers, and catalytic converters for automobiles.
3. Kitchenware: Stainless steel coil is commonly used to make cutlery, cookware, and kitchen appliances due to its resistance to corrosion, heat, and stains.
4. Medical: Stainless steel coil is used in medical equipment such as surgical instruments, implants, and diagnostic equipment due to its durability and biocompatibility.
5. Electronics: Stainless steel coil is used in electronics for components such as batteries, screens, and connectors due to its electrical conductivity and resistance to corrosion.
6. Aerospace: Stainless steel coil is used in the aerospace industry for applications such as aircraft frames, engine parts, and landing gears due to its strength, lightweight, and resistance to high temperatures.
7. Oil and gas: Stainless steel coil is used in the oil and gas industry for applications such as pipes, valves, and tanks due to its resistance to corrosion and high temperatures.

Through different processing methods of cold rolling and surface reprocessing after rolling, the surface finish of 201 stainless steel coils can have different types.
The surface processing of stainless steel coils is important to improve their performance and appearance. Some common surface treatments for stainless steel coils include:
1. Pickling: This process involves soaking the stainless steel coil in an acid solution, such as nitric or hydrofluoric acid, to remove any surface impurities and improve its corrosion resistance.
2. Passivation: This process involves treating the stainless steel coil with a chemical solution, such as nitric acid or sodium dichromate, to remove any surface iron and improve its resistance to corrosion.
3. Electro-polishing: This process involves passing an electric current through the stainless steel coil while it is immersed in an electrolyte solution to remove any surface imperfections and improve its appearance.
4. Coating: Applying a protective coating, such as paint or powder coating, to the surface of the stainless steel coil can help improve its durability, scratch resistance, and appearance.
5. Embossing: This process involves stamping a pattern or texture onto the surface of the stainless steel coil to add visual interest and texture.
6. Brushing: Brushing the surface of the stainless steel coil with a wire brush can create a uniform, directional grain pattern that can add to its appearance.
The specific surface treatment chosen for a stainless steel coil will depend on the desired properties and application of the coil.
The production process of stainless steel coil is: raw material preparation - annealing and pickling - (intermediate grinding) - rolling - intermediate annealing - pickling - rolling - annealing - pickling - leveling (finished product grinding and polishing) - cutting, packaging and storage .
