What are the different surfaces and applications of stainless steel?

Common mirror stainless steel is divided into 6K, 8K, 10K these three kinds. It is generally ordinary polishing, ordinary 6K, fine grinding 8K, super fine grinding 10K effect. The same thickness is generally not much difference, 10K mirror is brighter; The thicker the thickness, the worse the effect, the higher the processing cost. The processing grade, characteristics, polishing materials and uses of stainless steel surface are as follows:

Original surface: NO.1 surface treated with heat treatment and pickling after hot rolling. Generally used for cold rolling materials, industrial tanks, chemical industry equipment, etc., the thickness is from 2.0mm-8.0mm.

Blunt surface: NO.2D cold rolling after heat treatment, pickling, its material is soft, the surface is silver-white luster, for deep stamping processing, such as automotive components, water pipes and so on.

Fog surface: NO.2B cold rolling after heat treatment, pickling, and then finish rolling processing to make the surface for moderate brightness. Because the surface is smooth, easy to re-grind, make the surface more bright, widely used, such as tableware, building materials and so on. Almost all applications are satisfied with surface treatments that improve mechanical properties.

Coarse sand: NO.3 is used for grinding out the product with grain size 100-120 grinding belt. Has a better gloss, with discontinuous coarse grain. Used for interior and exterior decoration materials, electrical products and kitchen equipment, etc.

Fine sand: NO.4 Grinding products with 150-180 particle size grinding belt. Has a better gloss, with discontinuous coarse lines, stripes thinner than NO.3. Used in bath, building interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.

320: Product grinding out with particle size 320 grinding belt. Has a better gloss, with discontinuous coarse lines, stripes thinner than NO.4. Used in bath, building interior and exterior decoration materials, electrical products, kitchen equipment and food equipment.
