This type of stainless steel is titanium-stabilized and ferritic, designed to provide outstanding resistance to oxidation and corrosion, making it ideal for automotive and high-temperature uses. Aditya Stainless offers 409 Coils in a variety of thicknesses, widths, and surface finishes to cater to a wide range of industrial needs. Produced under strict international standards, these coils ensure dependable performance, excellent formability, and cost efficiency. Industries like automotive exhaust systems, heat exchangers, petrochemical processing, and architectural fabrication trust Aditya Stainless 409 Coils for their consistent quality and durability.
Stainless Steel 409 coil is a ferritic grade with a major content of iron, chromium (11-13%), and minor content of carbon, manganese, and silicon. Its excellent resistance to oxidation and corrosion makes it highly used in exhaust systems of automotive and heat exchangers. The mechanical properties of this alloy are good strength, high-temperature resistance, and moderate formability. The main advantages of the alloy are lower cost compared to other stainless steels, weldability, and resistance to sulfur compounds. It also provides resistance in moderately corrosive environments.
