SURFACE | CHARACTERISTIC | SUMMARY OFMANUFACTURING METHOD | APPLICATION |
NO.1 | Silvery white |
Hot rolled to
specified thickness |
Do not need to have aglossy surface use |
Lackluster | specified thickness | ||
NO.2D | Silvery white | After cold rolling, heat treatmentand pickling are caried out | General materia,deep material |
NO.2B | Gloss is stronger than NO.2D |
After NO.2D treatment,the final
light cold rlling is carried outthrough the polishing roller |
The general material |
light cold rlling is carried outthrough the polishing roller | |||
BA | As bright as a sixpence | No standard,but usually a brightannealed surface with high re-flectivity | Building materials,kitchen utensils |
NO.3 | Rough lapping | Grind with 100-200#(unit)strop tape | Building materials,kitchen utensils |
NO.4 | Intermediate grinding | Polished surface obtained by | Building materials,kitchen utensils |
grinding with150~ 180#stropabrasive tape | |||
NO.240 | Fine lapping | Grinding with 240# stropabrasive tape | Kitchenware |
