Product Detail

Product Detail

Shanghai Metal Corporation is specializing in the production of military and civilian dual-use corrosion resistant alloy, super alloy, precision alloy and other products. Products strictly implement the military standard, national standard, American standard, German standard, Japanese standard and other domestic and foreign production standards.

409L is a low-carbon, stabilized, ferritic stainless steel that provides improved corrosion resistance and weldability compared to standard Type 409. The addition of titanium in its composition helps stabilize the structure, making it less susceptible to intergranular corrosion after welding.

If you have any other questions about 409L products, please feel free to contact us, we’ll reply you within 24 hours.

Chemical Composition:
The composition typically includes:
Carbon (C): ≤ 0.03%
Chromium (Cr): 10.5 - 11.7%
Nickel (Ni): ≤ 0.5%
Manganese (Mn): ≤ 1.0%
Silicon (Si): ≤ 1.0%
Phosphorus (P): ≤ 0.04%
Sulfur (S): ≤ 0.03%
Titanium (Ti): 6 × (C+N) to 0.75%
Mechanical Properties:
Tensile Strength: 380 - 450 MPa
Yield Strength: 170 - 280 MPa
Elongation: ≥ 20%
Hardness: HRB ≤ 88
Plate, sheet and coil: ASTM A240, EN 10028-7, EN 10088-2, EN 10088-4
Bar and forging: ASTM A276, ASTM A479, ASTM A484 , EN 10088-3
Tube and pipe: ASTM A312

1. Corrosion Resistance: 409L offers moderate resistance to corrosion, particularly against exhaust gases, which makes it suitable for automotive applications such as exhaust systems.
2. Weldability: Excellent weldability due to its low carbon content and stabilization by titanium. Post-weld annealing is not generally required.
3. Formability: Good formability allows it to be easily formed into complex shapes.
4. Oxidation Resistance: 409L has good oxidation resistance.

1. Military: Exhaust systems, structural components.
2. Aerospace: Engine parts, heat shields.
3. Petrochemical: Piping, heat exchangers.
