304L stainless steel is low carbon steel, which is also the difference between it and 304 stainless steel. The corrosion resistance, appearance, workability, strength and other characteristics of 304L stainless steel far exceed those of other materials. Moreover, many surface treatment methods of stainless steel can obtain colorful colors and shapes, which have made great contributions to the development of stainless steel.
Surface treatment method and mechanical grinding surface treatment method in the manufacturing process of 304L stainless steel：
NO.1 Silver white, matt A rough, matte surface hot-rolled to a specified thickness, annealed and descaled No need for glossy surfaces
NO.2D Silver White Heat treatment and pickling after cold rolling, and sometimes a final light rolling on a matte roll. 2D products are used for applications that do not have strict surface requirements, general materials, deep drawing materials
NO.2B The gloss of NO.2B is stronger than that of NO.2D. After the NO.2D treatment, a final light cold rolling is carried out through a polishing roller to obtain proper gloss. This is the most commonly used surface finish and can also be used as a first step in polishing. General material
BA Mirror Bright No standard, but usually a bright annealed finish with a highly reflective surface. building materials, kitchen utensils
NO.3 Coarse grinding: Use 100~200# (unit) abrasive belts to grind NO.2D and NO.2B materials for building materials and kitchen utensils
NO.4 Intermediate grinding The polished surface obtained by grinding the NO.2D and NO.2B materials with a 150~180# grain abrasive belt is universal, with specular reflection and visible 'grain' bright Same as above
NO.240 Fine grinding Grind the NO.2D and NO.2B materials with 240# grain grinding belt. Kitchen utensils
NO.320 Ultra-fine grinding Grind the NO.2D and NO.2B materials with 320# grain grinding belt Same as above
NO.400 The gloss is close to BA. Grind the NO.2B material with a 400# polishing wheel. General materials, construction materials, kitchen utensils
HL Hairline Grinding Hairline grinding with appropriate particle size abrasives (150~240#), which has a lot of grains Building, construction materials
NO.7 is close to mirror surface grinding. Use 600# rotary polishing wheel for grinding. For art and decoration
NO.8 Mirror surface grinding Mirror with polishing wheel for grinding Reflector, for decoration

China Factory Steel Strip 304L Stainless Steel Coil Strip contains 18% chromium and 8-10% nickel. 304L stainless steel with ultra-low carbon, more resistant to intergranular corrosion. At the same time, it is beneficial to the stretching of some stamping parts.
China Factory Steel Strip 304L Stainless Steel Coil Strip has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. China Factory Steel Strip 304L Stainless Steel Coil Strip is generally used for processing into small diameter steel pipes, such as stainless steel water pipes, stainless steel decorative pipes, heat exchange pipes, square pipes, stainless steel coil pipes and so on.
