Product Description
JIS G4312-2019 JIS G4305 SUH409L Cold Rolled Stainless Steel Coil Strip
AISI 409L stainless steel strip and SUH409L stainless steel coil are premium cold rolled steel sheets designed for decorative construction applications. Compared with ordinary carbon steel, stainless steel features enhanced alloying elements including Cr, Ni, Mn, and Mo, resulting in superior material characteristics.
Cold Rolled Steel Sheet in Coil 409L Stainless Steel for Decoration Construction
The corrosion resistance of stainless steel primarily depends on chromium content, while molybdenum and nitrogen further enhance corrosion resistance. Nickel ensures optimal microstructure and mechanical properties.

Surface Finishes
| Finish | Description & Processing |
|---|---|
| No.4 | Good gloss with fine surface lines. Processing: Polishing and tempering rolling of 2D products or 2B with 150-180 abrasive material (JIS R6002). |
| HL | Silver-gray with hair streaks. Processing: Polish 2D or 2B products with suitable abrasive material for continuous grain appearance. |
| 8K | Mirror state surface. Processing: 2D or 2B products ground and polished to mirror effect with suitable abrasive material. |
| 2B | Silvery white with superior gloss and flatness compared to 2D. Processing: Hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling. |
| BA | Excellent surface gloss with high reflectivity, similar to mirror surface. Processing: Hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenched and tempered rolling. |
| 1D | Discontinuous particle surface, also known as matte. Processing: Hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. |
| 2D | Slightly shiny silvery white. Processing: Hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. |
| No.3 | Better gloss with rough surface. Processing: Polishing and tempering rolling of 2D products or 2B with 100-120 abrasive materials (JIS R6002). |
| SB | Smooth surface with clear, delicate texture and comfortable appearance. Widely praised in kitchen appliance applications. |
