409L Stainless Steel Sheet Price Per Kg – 2026

As of January 7, 2026, the spot price for cold-rolled 409L stainless steel sheets is 7.35 RMB/kg (approximately US$1.03/kg). Typical prices for large orders (over 10 tons) range from 7.00-8.00 RMB/kg (approximately US$0.98-1.12/kg), with specific prices varying depending on thickness (0.3-12 mm), width (1000-2000 mm), surface finish (2D/2B/BA), and certification requirements (ASTM A240/AMS 5504).

 

409L Stainless Steel vs. 304: Cost
409L stainless steel offers a 30-40% cost advantage compared to 304 (currently priced at 14.20 RMB/kg for cold-rolled). Prices are expected to remain within a narrow range of 6.80-7.80 RMB/kg during the first quarter of 2026, influenced by factors such as raw material costs (chromium: US$8.5-9.0/kg, titanium: US$35-38/kg) and demand from the automotive industry (its main application area, accounting for 65% of consumption).

 

What Is 409L Stainless Steel Sheet?

409L stainless steel is a ferritic low-carbon stainless steel with 10.5–11.5% chromium and ≤0.03% carbon. Its low carbon content minimizes carbide precipitation during welding, making it ideal for automotive exhaust systems, industrial ducting, and structural applications where corrosion resistance is needed at a cost-effective price.

Key Features:

Magnetic ferritic structure

Good weldability and formability

Moderate corrosion resistance

Cost-effective alternative to 430 stainless steel in certain applications.

How does 409L compare with 430 stainless steel in corrosion resistance?
409L stainless steel offers lower corrosion resistance than 430 stainless steel in general environments but provides sufficient resistance to oxidation and mild corrosion, making it suitable for automotive exhaust applications.

 

What thicknesses and widths are available for 409L sheets?
409L stainless steel sheets are typically available in thicknesses ranging from 0.4 mm to 6 mm and standard widths up to 1,500 mm, with custom sizes available upon request.

 

Can 409L stainless steel sheet be used for automotive exhaust systems?
Yes, 409L stainless steel sheets are widely used in automotive exhaust systems due to their good high-temperature oxidation resistance, cost-effectiveness, and ability to form complex shapes.

 

Is 409L stainless steel magnetic?

409L stainless steel is magnetic because it is a ferritic stainless steel, which allows it to retain magnetic properties even after welding or forming.
