Stainless steel sheet Surface Finish Introduction
Charecteristics and Application
2B
The surface brightness and flatness of 2B is better than 2D then theough a special surface treatment to improve its mechanical properties,2B could nearly Satisfy comprehensive uses
No.3
Polished with abrasive belt of git#100#200#,have better brightness with discontinuous coarse stria used as inner and external omaments for building, electrical appliances and kitchen utensils etc.
No.4
Polished with abrasive belt of grit#150#180,have better brightness with discontinuous coarse stria, but thinner than NO.3, are used as bathtub buildings inner and extemal omaments electrical appliances kitchen utensils and food processing
BA
Cold rolled, bright annealed and skin-passed, the product have excellent brightness and food reflexivity like mirrorm kitchen apparatus, omament etc.
8K
The product have excellent brightness and prefer reflexivity can be the mirror.
HL
Polished with abrasive belt of trit#150#320 on the NO.4 finish and has continuous streaks, mainly used as buildings omaments elevators, door of building, frontal plate etc.
