Characteristics & Application

NO 1

Hot-rolled surface,annealed and pickled,can be used as cold-rolling material,industial tanks   and chem i cal devices.

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.

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.

#320

Polished with abrasive belt of grit #320, have better brightness with discontinuous coarse stria,

but thinner NO.3, are used as bathtub building   inner and external ornaments electrical

appliances kitchen utensils and food lprocessing equipment etc.

HL

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
