Stainless steel has unique strength, high wear resistance, excellent corrosion resistance, not easy to rust. Stainless steel materials are widely used in various industries: food machinery, mechanical and electrical industry, home appliance industry, decoration and so on.
At the same time, the application and development of stainless steel depends on the development of surface treatment technology to a certain extent. With the development of the industry and the market, the demand for stainless steel surfaces is diverse and of high quality.
There are many kinds of stainless steel surfaces, each of which has its own representative. The following is the representation method and related introduction of the stainless steel surface state sorted out by Lishun Stainless steel.
No.1 is a rough and matte surface that is hot rolled to the specified thickness, annealed and descaled. It is suitable for applications that do not need surface gloss.
No.2D is a kind of matte surface processing that heat treatment and pickling are carried out after cold rolling, and sometimes the final light rolling is carried out on the roughing roller. 2D products are used for purposes with lax surface requirements, general materials and deep drawing materials.
2B is stronger than No.2D. After 2B treatment, it is subject to a light cold rolling through the polishing roller to obtain appropriate gloss. This is a common surface machining, which can also be used as a polishing tool.
BA is as bright as a mirror and has no standard, but it is usually the surface processing of bright annealing, with high surface reflectance. Commonly used in building materials, kitchen equipment, etc.
No.3 rough grinding is obtained by grinding No.1, 2b and other materials with 100-200 # (abrasive belt roughness unit) abrasive belt. Commonly used in decoration, kitchen utensils, etc.
No.4 intermediate grinding grind No.1, 2b and other materials with 150-180# abrasive belt to obtain a polished surface. This is a general-purpose, shiny surface with visible 'grains' with a certain specular reflection. It is commonly used in mechanical equipment frame, elevator car, various tank bodies, etc.
No.7 is close to mirror grinding, and 600# rotary polishing wheel is used for grinding. For art and decoration.
8K mirror grinding is a bright mirror state obtained by repeated grinding with a polishing wheel. Internal and external walls and decoration of special equipment.
