The surface brightness and flatness of no2B is better than no2D. then through a   special

surface   treatment   to improve its mechanical properties,No2B could nearly satisfy   compreh

ensive uses.

The surface is finished by heat treatment and pickling or   processes corresponding   thereto

after   hot rolling.

Polished with abrasive belt of grit #150-#180,have better brightness with   discontinuous

coarse   stria, but   thinner than No3,   are used as bathtub   buildings   inner   and   external

ornaments   electrical   appliances kitchen utensils and food processing equipment etc.

Polished with abrasive belt of grit #150#320 on the NO.4 finish and has continuous

streaks, mainly used   as buildings ornaments elevators,door of building, frontal plate   etc.

Cold rolled, bright annealed and skin-passed, the product   have excellent brightness

and   good reflexivity   like mirror,kitchen   apparatus,ornament etc.
