Oct 31, 2017

1D—Surface with discontinuous granular, also known as matte. 

Processing: hot rolling + annealing, shot peening, pickling + cold rolling + annealing, pickling


2D— Slightly shiny silver white. 

Processing technique: hot rolled + annealing, shot peening, pickling + cold rolling +annealing, pickling


2B—Silver white, better glossiness and flatness than that of 2D surface. 

Processing technique: hot-rolling+annealing, shot peening and pickling +cold rolling + annealing, pickling + conditioning rolling.


BA—Excellent surface glossiness, high reflectivity, like the mirror surface. 

Processing technology: hot rolling + annealing, shot peening, pickling + cold rolling + annealing, pickling + surface polishing + conditioning rolling.


No.3—Good glossiness, coarse grain surface. 

Processing: polishing and conditioning, rolling 2D/2B products with 100~120 abrasive substance.  


No.4—Good glossiness, fine lines on surface. 

Processing technique: polishing, conditioning and rolling 2D products/2B products with 150~180 abrasive materials (JIS R6002).


HL—Silver gray and with hair stripes. 

Processing technique: polishing 2D product or 2B product with proper sized grinding materials and continuous abrasion pattern on surface.


Mirror—In the mirror state. 

Processing technique: grinding and polishing 2D or 2B products with appropriate sized abrasive materials to mirror effect.
