Surface categories of stainless steel

Now the development of stainless steel, has made the corrosion resistance, appearance, processability, strength and other characteristics of stainless steel far more than other materials, and, many surface treatment method of stainless steel, you can obtain a colorful color and shape, which makes a great contribution to the development of stainless steel.

Surface Features Outline of manufacturing method Uses
NO.1 Silvery white, lusterless Hot rolled to a specified thickness, then annealed and descaled to a rough, non-glossy surface Uses that do not require a glossy surface
NO.2D Silver White After cold rolling, heat treatment and pickling, and sometimes a final light rolling process in the rough rolls, a non-glossy surface finish 2D products are used for applications that do not require a strict surface, for general use, and for deep-drawing.
NO.2B Shine stronger than NO.2D After the NO.2D treatment, it is subjected to a final light cold roll by polishing rollers to obtain the proper gloss. This is the most commonly used surface finish, which can also be used as the first step in polishing General Materials
BA Shiny as a mirror No standard, but usually bright annealed surface finish with high surface reflectivity. Construction materials, kitchen appliances
NO.3 Coarse grinding Grind the NO.2D and NO.2B materials with 100~200# (unit) grinding belt. Construction materials, kitchen appliances
NO.4 Moderate grinding The polished surface obtained by grinding NO.2D and NO.2B materials with 150~180# grinding belt is a general-purpose, mirror-reflective, bright surface with visible ‘grains’. Construction materials, kitchen appliances
NO.240 Fine grinding Grind NO.2D and NO.2B materials with 240# grinding belt. Kitchen utensils
NO.320 Extremely fine grinding Grind NO.2D and NO.2B material with 320# grinding belt. Kitchen utensils
NO.400 Glossy close to BA Grind NO.2B material with 400# polishing wheel General materials, construction materials, kitchen appliances
HL Ripple grinding Abrasive material with appropriate particle size for pattern grinding (150~240#) has a large number of main particles. Buildings, building materials
NO.7 Close to mirror polishing Grinding with 600# rotary polishing wheel For art, for decoration
NO.8 Mirror grinding Mirror grinding with polishing wheel Reflective mirror, for decoration
