409L Stainless Steel Coil Strip
AISI 409L stainless steel strip and SUH409L stainless steel coil are premium cold rolled steel sheets designed for decoration and construction applications. These materials feature enhanced chemical composition with alloying elements that provide superior corrosion resistance and mechanical properties compared to ordinary carbon steel.
Key Advantages: Compared with ordinary carbon steel, stainless steel contains increased levels of alloying elements such as Chromium (Cr), Nickel (Ni), Manganese (Mn), and Molybdenum (Mo), resulting in significantly different material characteristics. The corrosion resistance primarily depends on Chromium content, while Nickel ensures optimal microstructure and mechanical properties.

Surface Finishes
| Finish Type |
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 hair streaks. Processing: Polishing 2D or 2B products to create continuous grain appearance. |
| 8K |
Mirror finish state. Processing: Grinding and polishing 2D or 2B products to mirror effect. |
| 2B |
Silvery white with better gloss and flatness than 2D surface. Processing: Hot rolling + annealing + pickling + cold rolling + annealing pickling + quenching. |
| BA |
Excellent surface gloss with high reflectivity, similar to mirror surface. Processing: Hot rolling + annealing + pickling + cold rolling + surface polishing. |
| 1D |
Discontinuous particle surface, also known as matte. Processing: Hot rolling + annealing + pickling + cold rolling. |
| 2D |
Slightly shiny silvery white. Processing: Hot rolling + annealing + pickling + cold rolling. |
| No.3 |
Better gloss with rough surface. Processing: Polishing and tempering rolling with 100-120 abrasive materials. |
| SB |
Smooth surface with clear texture, delicate appearance, and high-grade aesthetic. Popular in kitchen appliances. |
