409 Stainless Steel Strip
What is 409 Stainless Steel Strip?
Alloy 409 is a versatile ferritic stainless steel, stabilized with chromium and titanium, primarily employed in automotive exhaust systems. With a minimum of 11% chromium, it forms a passive surface film essential for stainless steel corrosion resistance. This alloy offers excellent resistance to high-temperature corrosion, combined with moderate strength, good ductility, and cost-effectiveness.
Alloy 409 surpasses carbon steel in corrosion resistance, making it a preferred choice in mildly aggressive environments where its ability to resist corrosion and oxidation at elevated temperatures provides significant benefits. It finds application where mechanical properties and corrosion resistance are paramount, prioritizing function over appearance.

409 Stainless Steel Strip FAQ
Q: What is 409 stainless steel strip used for?
A: 409 stainless steel strip is used in a variety of applications due to its excellent heat resistance, corrosion resistance, and formability.
Q: Is 409 stainless steel strip magnetic?
A:Yes, 409 stainless steel is a ferritic stainless steel, which typically contains iron and chromium but has a low carbon content. Ferritic stainless steels are known for their magnetic properties. This magnetic nature is due to their body-centered cubic (BCC) crystal structure, which allows the alignment of magnetic domains.
Q: What are the mechanical properties of 409 stainless steel strip?
A: The mechanical properties of 409 stainless steel strip can vary depending on factors such as the processing method (annealed or cold rolled) and the specific temper condition.
Q: Can 409 stainless steel strip be used in high-temperature environments?
A: No,409 stainless steel strip is generally not recommended for continuous high-temperature applications where temperatures exceed about 600°C (1112°F). While it has good heat resistance compared to carbon steels, it has limitations due to its ferritic structure and composition.
Q: How to choose a 409 stainless steel supplier?
