Stainless steel surface processing grades, features and uses Rolled surface processing. There are three basic rolling surface processes for sheet and strip, which are represented by the production process of sheet and strip.
No. 1: After hot rolling, annealing, pickling and descaling. The treated steel surface is a dull surface and somewhat rough. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc. Thicker by 2.0MM-8.0MM.
NO.2: After the cold rolling, the material is soft and the surface is silver white luster after heat treatment and pickling. It is used for deep drawing processing, such as automobile components, water pipes, etc.
NO.2B: After cold rolling, heat treatment, pickling, and finishing are used to make the surface a moderate brightness. Because the surface is smooth, easy to re-grind, so that the surface is more bright, widely used, such as tableware, building materials. After surface treatment with improved mechanical properties, almost all applications are satisfied.
BA Bright Annealing: Products that are brightly annealed and flattened after cold rolling. Excellent surface gloss and high reflectivity. Like a mirror surface. For home appliances, mirrors, kitchen equipment, decorative materials and so on.
Polished surface processing:
NO.3: Products ground with a 100-120 grinding belt. Better gloss with discontinuous coarse pattern. Used for interior and exterior decoration materials, electrical products and kitchen equipment.
3A: The surface is uniformly ground and the abrasive grain size is 80-100.
3B: The matte surface is polished, and the surface is evenly ruled. Usually, the abrasive belt with a grain size of 180-200 is polished once on a 2A or 2B plate.
NO.4 (240#): Products ground with No. 240 grinding belt. With better gloss, with a discontinuous coarse pattern, the stripe is thinner than NO.4. For baths, interior and exterior decorative materials, electrical products, kitchen equipment and food equipment.
No.6(320#): A product ground with a No. 320 grinding belt. With better gloss, with a discontinuous coarse pattern, the stripes are finer than 240#. For baths, interior and exterior decorative materials, electrical products, kitchen equipment and food equipment.
No.7(400#): A product ground with a No. 400 grinding belt. With better gloss, with a discontinuous coarse pattern, the stripes are thinner than 320#. For baths, interior and exterior decorative materials, electrical products, kitchen equipment and food equipment.
No.8: The mirror-polished surface has a high reflectance and is often referred to as a mirror-finished surface because it reflects the image clearly.
Hairline HAIRLINE: HL NO.4 is a product with a continuous pattern of polished belts of appropriate grain size to produce a pattern (Subdivision No. 150-320). Mainly used for building decoration, elevators, doors, panels of buildings, etc.
