Product Description

EN DIN 1.4512 Standard 409L Stainless Steel Strip for Exhaust System

AISI 409L stainless steel strip, also known as SUH409L stainless steel coil, is a cold-rolled steel sheet specifically designed for exhaust systems and decorative construction applications.

Compared with ordinary carbon steel, stainless steel features enhanced chemical composition with 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
No.4	Good gloss with fine surface lines. Processing: Polishing and tempering rolling of 2D/2B products with 150-180 abrasive material.
HL	Silver-gray with hairline streaks. Processing: Polishing 2D/2B products with appropriate abrasive material for continuous grain appearance.
8K	Mirror finish state. Processing: Grinding and polishing 2D/2B products to mirror effect with suitable abrasive material.
2B	Silvery white with superior gloss and flatness compared to 2D. Processing: Hot rolling + annealing + pickling + cold rolling + annealing pickling + tempering rolling.
BA	Excellent surface gloss with high reflectivity, similar to mirror surface. Processing: Hot rolling + annealing + pickling + cold rolling + annealing pickling + surface polishing + tempering rolling.
1D	Matte surface with discontinuous particles. Processing: Hot rolling + annealing + pickling + cold rolling + annealing pickling.
2D	Slightly shiny silvery white. Processing: Hot rolling + annealing + pickling + cold rolling + annealing pickling.
No.3	Better gloss with rough surface. Processing: Polishing and tempering rolling of 2D/2B products with 100-120 abrasive materials.
SB	Smooth surface with clear texture, delicate grain, comfortable appearance, and high-grade aesthetic. Widely preferred in kitchen appliances.
