Stainless steel processing involves various techniques such as cutting, folding, bending, and welding to transform stainless steel into products with the desired properties for industrial use. This process requires a range of specialized machinery, tools, and equipment. Stainless steel processing equipment can be categorized into two main types: shearing equipment and surface treatment equipment. Shearing equipment further divides into open flat equipment and slitting equipment. Additionally, based on the thickness of the stainless steel, there are options for both cold and hot rolling processing equipment. Thermal cutting methods primarily include plasma cutting, laser cutting, and water jet cutting.
Stainless Steel Surface Finishes
Original Surface (NO.1): This surface undergoes heat rolling followed by heat treatment and pickling. Typically used for thicker cold-rolled materials, industrial tanks, and chemical equipment, ranging from 2.0mm to 8.0mm thick.
Matte Surface (NO.2D): After cold rolling, heat treatment, and pickling, this surface is softer and retains a silvery-white appearance. Ideal for deep drawing applications like automotive components and water pipes.
Bright Annealed Surface (NO.2B): Following cold rolling, heat treatment, pickling, and finishing, this surface achieves a moderately bright finish. Its smooth texture makes it easy to re-polish for a more reflective appearance, widely used in tableware and construction materials. With proper surface treatments, it meets almost all functional requirements.
Coarse Sand Finish (NO.3): Ground using a 100-120 grit belt, this finish offers good luster with discontinuous rough lines. Commonly found in interior and exterior decorative items, electrical products, and kitchen equipment.
Fine Sand Finish (NO.4): Produced with a 150-180 grit belt, this finish provides enhanced brightness with finer striations compared to NO.3. Widely used in bathrooms, interior and exterior decor, electrical goods, kitchenware, and food equipment.
#320 Finish: Ground with a 320 grit belt, it exhibits superior gloss with finer striations than NO.4. Suitable for bathrooms, interior and exterior decoration, electrical products, kitchen equipment, and food-grade applications.
Hairline Finish (HLNO.4): Created by continuous grinding with an appropriate grit belt, resulting in uniform grain patterns (ranging from 150 to 320 grit). Primarily used in architectural design, elevator interiors, door panels, and other decorative elements.
Polished Finish: Achieved through bright annealing after cold rolling and smoothing, offering exceptional surface shine and high reflectivity akin to a mirror-like finish. Often used in home appliances, mirrors, kitchenware, and decorative materials.
Applications Across Industries
In architectural settings, the choice of stainless steel surface finish plays a crucial role, especially in environments prone to corrosion. Smooth surfaces are preferred since they resist dirt accumulation, which could otherwise lead to rusting or corrosion.
Elevator decorative panels in large halls frequently utilize stainless steel due to its durability and aesthetic appeal. While fingerprints may appear, selecting the right surface finish can mitigate visibility issues and maintain visual clarity.
Many industries prioritize hygiene, including food processing, catering, brewing, and pharmaceuticals. Here, surfaces need regular cleaning and are often exposed to chemical agents. Stainless steel excels in these contexts due to its ease of maintenance and resistance to bacterial growth, matching the cleanliness standards of glass and ceramic materials.
Hospitals and similar environments demanding strict hygiene benefit significantly from stainless steel's non-porous nature and antimicrobial properties. These qualities ensure that daily cleaning routines, supported by occasional chemical cleansers, keep surfaces pristine while discouraging microbial proliferation.
Cleaning stainless steel requires attention to its directional polishing lines to avoid damaging the finish. For optimal results, wiping should follow these lines, ensuring longevity and maintaining the material’s natural luster.
