409 Stainless Steel Pipe Supplier in China
Your Trusted 409 SS Tube Manufacturer
The 409 stainless steel pipe is a type of ferritic stainless steel that can be used as a replacement for carbon steel in mild environments. It offers excellent formability, allowing it to be shaped into various complex forms through roll forming, stretch bending, deep drawing, or pressing. But this kind of stainless steel pipe can’t be heat treatable.
At Tuolian, we provide customized services for 409 stainless steel pipes, offering different sizes, surface finishes, and various grades. Feel free to send us your requirements.
Key Features of 409 SS Tube
409 stainless steel pipes have several notable advantages, including great corrosion resistance, good formability, medium strength, and high-temperature oxidation resistance. Its excellent formability makes it a suitable choice for certain exhaust systems.


Applications of 409 SS Tube
409 stainless steel pipes are commonly used in exhaust systems, such as catalytic converters, mufflers, tailpipes, and heat exchanger tubing. Additionally, our 409 stainless steel pipes can also be utilized for structural support and hangers, transformer cases, furnace components, farm equipment like spreaders, gas turbine exhaust silencers, and tubular manifolds.

Apart from pipe form, our 409 stainless steel can be customized into various shapes for different applications, including sheets, sheet coils, plates, round bars, processed flat bars, and tubular products.

We offer several end condition options for your convenience, including haven cut, brushed deburred, end facing, mill cut, saw cut, and chamfering.

Our 409 stainless steel pipes come in different shapes, such as D-shape, square, oval, rectangle, Double-D, round, and specialty shapes.
In summary:
409 stainless steel: Good for automotive exhaust systems, offers moderate corrosion resistance and good mechanical properties, but lower heat resistance.
304 stainless steel: Excellent corrosion resistance, higher heat resistance, widely used in various industries including food processing and chemical processing.
Yes, 409 stainless steel is magnetic. It belongs to the ferritic stainless steel family, which is generally magnetic in nature. The magnetic properties of stainless steel are primarily influenced by its microstructure, and ferritic stainless steels like 409 have a microstructure that allows them to exhibit magnetic behavior.
The lifespan of 409 stainless steel can vary depending on the application and environmental conditions. In automotive exhaust systems, it can last around 8 to 12 years or longer. Factors such as maintenance, exposure to corrosive substances, and high temperatures can affect its lifespan. Proper care and maintenance can help extend its life.
