Surface Finish
Surface finish | Characteristics & Application |
NO.1 | Hot-rolled surface, annealed and pickled, can be used as
cold-rolling material,industial tanks and chem i cal devices. |
NO.2D | Cold-rolled, an nealed and pick led with out skinpassing the dull
prod ucts can be used as auto mo bile parts, build ing materrials
and pipings. |
NO.2B | The surface brightness and flatness of NO.2B is better than NO.2D.
Then through a special surfacetreament to improve its mechamical
properties, N02B could nearly satisfy com pre hen sive uses. |
NO.3 | Polished with abra sive belt of grit #100#120,have bet ter bright
ness with dis con tin u ous coarse stria, used as in ner and ex ter
nal or na ments for building, elec tri cal ap pli anc es and
kitchen uten sils 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 bathtud buildinginner and external ornaments electrical
appliances, kitchen utensils and food processing equipment etc. |
HL | Polished with abrasive belt of grit #150-320 on the No.4 finish and
has continuous streaks, mainly used as building ornaments,
elevators, door of building, frontal plate etc. |
BA | Cold rolled, bright an nealed and skin passed, the prod uct has ex
cel lent bright ness and good re flex iv i ty like mirror, used for
lectrical appliances, mirror, kitch en apparatus, or na ment ma te
ri als etc. |
Good weldability and flame cutting, nonmagnetic. The shipbuilding industry, welded constructions.
