Surface code, processing methods
| Surface | Surface code | Processing method |
| bright surface |
BA |
After cold rolling with appropriately sized rolls, final annealing in a controlled atmosphere annealing furnace maintains a bright cold rolled surface |
| Temper Rolled surface |
TR |
After cold rolling of rollers with proper articles, it gets the cold rolling surface of special surface roughness with regulated performance |
| Capillary crack surface |
HL |
After mill roll of rollers with proper articles the steel band surface demonstrates lackluster lengthways polished abrasion pattern with a certain length |
| Capillary crack surface |
WF |
After mill roll of rollers with proper articles, the steel band surface demonstrates lackluster lengthways polished abrasion pattern with a certain length (length of abrasion pattern shorter than that of HL) |
| Sand-blasting surface |
SF |
After mill roll of rollers with proper articles, the steel band surface demonstrates unordered dotted abrasion patterns |
