409L Stainless Steel Coil Strip
AISI 409L stainless steel strip and SUH409L stainless steel coil are premium cold-rolled steel products designed for decorative and construction applications. These materials feature enhanced corrosion resistance and mechanical properties compared to standard carbon steel.
Cold Rolled Steel Sheet in Coil 409L Stainless Steel for Decoration & Construction
Stainless steel differs from ordinary carbon steel through the addition of alloying elements such as Chromium (Cr), Nickel (Ni), Manganese (Mn), and Molybdenum (Mo). The corrosion resistance primarily depends on Chromium content, while 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 or 2B products with 150-180 abrasive material. |
| HL |
Silver-gray with hairline streaks. Processing: Polishing 2D or 2B products with suitable abrasive material for continuous grain appearance. |
| 8K |
Mirror finish state. Processing: Grinding and polishing 2D or 2B products 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 finish. Processing: Hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. |
| 2D |
Slightly shiny silvery white surface. Processing: Hot rolling + annealing shot peening pickling + cold rolling + annealing pickling. |
| No.3 |
Better gloss with rough surface texture. Processing: Polishing and tempering rolling of 2D or 2B products with 100-120 abrasive materials. |
| SB |
Smooth surface with clear, delicate texture and sophisticated appearance. Widely praised in kitchen appliance applications. |
