Classification of surface stainless steel

Surface	Feature	Manufacturing Method	Usage
NO.1	Silvery white, dull	Hot rolled to specified thickness	It does not need to have a shiny surface
NO.2D	Silvery white	After cold rolling, heat treatment and pickling are carried out	Common material, deep drawing wood
NO.2B	Luster is stronger than No.2D	After NO.2D treatment, a final light cold rolling is carried out on a polishing roll	Common material
BA	as bright as a sixpence	Non standard, but usually bright annealed surface finish with high surface reflectivity.	Building materials, kitchen utensils
NO.4	Grind	A polished surface obtained by grinding with a 150~180# abrasive belt	Building materials, kitchen utensils
NO.240	Fine grind	Grind with a 240# strop abrasive belt	kitchen utensils
NO.320	Very fine grinding	Grind with a 320# strop abrasive belt	kitchen utensils
NO.400	The gloss is close to BA	Grind with 400# polishing wheel	Common material,Building materials, kitchen utensils
HL	Hairline grinding	It has a large number of whetstone grains when it is used for grain grinding (150~240#)	Buildings, building materials
NO.8	Mirror	The mirror is ground with a polishing wheel	Reflector, decorative
