The stainless steel surface processing grades are analyzed in detail from the following eight aspects: NO.1 The surface after the hot rolling is subjected to a heat treatment and a pickling treatment. Generally used for cold-rolled materials, industrial tanks, chemical industry equipment, etc. Thicker by 2.0MM-8.0MM.
Blunt surface: NO.2D cold-rolled after heat treatment, pickling, its soft material, the surface was silvery white luster, used for deep stamping processing, such as automotive components, water pipes.
Matte: NO.2B After cold rolling heat treatment, pickling, and then finishing the surface to make the surface of 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.
Grit No. 3 The product ground with a No. 100-120 grinding belt. Better gloss with discontinuous coarse pattern. Used for interior and exterior decoration materials, electrical products and kitchen equipment.
Fine sand: NO.4 Grinding with 150-180 grain size. With better gloss, with a discontinuous coarse pattern, the stripes are thinner than NO.3. For baths, interior and exterior decorative materials, electrical products, kitchen equipment and food equipment.
#320 Polished product with No. 320 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.
Hairline HAIRLINE: HLNO.4 A product with a continuous pattern of polished belts of appropriate grain size to produce a pattern (subdivision 150-320). Mainly used for building decoration, elevators, doors, panels of buildings, etc.
Glossy surface: After BA, it is brightly annealed and then smoothed. Excellent surface gloss and high reflectivity. Like a mirror surface. For home appliances, mirrors, kitchen equipment, decorative materials and so on.
