|---|---|---|---|
| No.2B | When finishing acid cleaning by heat treatment or equivalent processing, temper cold rolling is performed till proper gloss is acquired (it shows better gloss and flatness than No. 2D) | Common type of cold rolling products, used for general purposes |  |
| No.4 | Grinding is performed by No. 150 ~ 180 according to regulation of KS L 6001 (Grain size of abrasive). It shows smoother grind condition than No. 3 | Construction, kitchen products, automobile, medical appliances, food facility, etc |  |
| BA | After cold rolling, dazzling heat treatment is performed to improve reflectivity and gloss | Automobile parts, home appliances, kitchen products, decorations, construction, etc |  |
| HL | It uses abrasive, which has proper grain size, so that it can show continuous grinding pattern | General products for construction material |  |
| No.8 (ASTM A480 No.7) |
It has excellent gloss, reflectivity and sign of grinding by rotating buff using products over 800 Mesh (dry corrosion) | Construction, reflector, substitution of platen, decorations |  |
| MR | It has high gloss, reflectivity and no sign of grinding by rotating buff using products over 1000 Mesh (dry corrosion) | Construction, reflector, substitution of platen, decorations |  |
| EM | Cold rolling is performed by embossing roll, which has carved pattern engraved using etching or electric discharging | Construction, interior for elevator, substitution of platen, electronic part, decorations |  |
| BB | After cold rolling, dazzling heat treatment is performed to give metallic luster | General purpose, such as home appliances, kitchen products |  |
| Classification | Embossing | Etching |
|---|---|---|
| Advantage | - Available for mass production - Prevention of surface contamination and improvement of corrosion resistance with slow curve - Available for depth control by use (Reproducibility) - Available for double pattern |
- Available for various patterns - Relatively small restriction on pattern designs |
| Disadvantage | - Limited pattern (work roll processing) - Limited pattern design (Size, form) |
- Low productivity - Small production (High price) - Environmental problems caused by strong acid - Corrosion pattern can cause surface contamination and corrosion |
| Use | - Material for Construction, kitchen products, decoration pipe, electronic parts | |
| Others | - Having high corrosion resistance, which is unique property of stainless steel, Excellent moldability | |
