Stainless Steel  409L (UNS S40900, EN 1.4512) is a kind of stabile version of 409, composed with proper chromium, low composition of carbon and nitrogen and adjunction of titanium, all composition appropriate make Grade 409L products have some properties, Corrosion Resistance, Weldability and Formability. Due to the lower chromium, Grade 409L was another low cost option for corrosion resistant stainless steel.

Grade 409L has a good combination of Heat Resistance and Corrosion Resistance, can be ideal for non- or lightly corrosive environments or applications. It has excellent oxidation resistance in high temperatures and good welding performance, which can be used for automotive exhaust pipes or oil equipment.

Grade 409L may be considered for a wide variety of applications where one or more of the following properties are important:
