The surface of stainless steel marking method
Atmospheric oxidation in the general environment, the corrosion rate of stainless steel is very low, is not no rust, as chromium (Cr), the formation of very dense on the surface of the thin chromium oxide (Cr2O3) film, to prevent continued corrosion rust derived from name. Its corrosion resistance, oxidation resistance, low heat conductivity and good processing properties.
The original surface: NO.1
Heat treatment after hot rolling, pickling are commonly used in the general corrosion resistance of heat, such as the chemical tank and so on, the thickness of thicker from 2.0MM-8.0MM.
Blunt surface: 2D
Heat treatment after cold rolling, pickling, and its texture is soft, shiny silver-white surface for stamping deep processing, such as automotive components, plumbing and so on.
Matte: 2B
Heat treatment after cold rolling, pickling, and then finishing the surface for processing the light from a moderate. As a result of a smooth surface, easy to re-grinding, so that the surface of a more bright, wide range of uses, such as tableware, building materials and so on.
Bright side: BA
After the implementation of cold-rolled heat-hui surface, the surface is more light, commonly used in electrical appliances, kitchenware and decorative, such as construction.
Silk hair surface: HAIR LINE
Appropriate size of the abrasive materials to cause a row stripes processors, commonly used in construction decoration, such as elevators, escalators, etc., uses a wide range.
Fine sand: NO.4
No. 150-180 abrasive particle size in materials processing, and are commonly used in dairy food processing equipment, medical equipment and so on.
Coarse sand: NO.3
No. 100-120 abrasive particle size in materials processing, and are commonly used in dairy food processing equipment, kitchen utensils
