Product Description of 409 Stainless Steel Welded Tube
Introducing Grade 409 Stainless Steel Welded Tube, a versatile and reliable tubing solution for various industrial applications. With its 11% chromium content, this stabilized ferritic stainless steel offers excellent oxidation and corrosion protection, surpassing the capabilities of carbon steel and coated steel. While it may have lower corrosion resistance compared to grades like 304, 430, or 439, Grade 409 still outperforms mild carbon steel in this aspect. Formability is another advantage of 409, allowing for roll forming, stretch bending, deep drawing, and pressing. When cold work using mild techniques, the annealed condition of Grade 409 does not harden. Welding performance is fair, but caution should be exercised in impact-loaded structures to prevent grain structure growth in heat-affected zones. Trust in the quality of Grade 409 stainless steel welded tube, an ideal choice for applications requiring excellent oxidation resistance and corrosion protection, available from Huaxiao stainless steel tube suppliers.

Features of 409 Stainless Steel Welded Tube
Grade 409 exhibits good resistance to corrosion from atmospheric conditions and exhaust gases. While slight surface rust may develop, it acts as a protective layer, inhibiting further corrosion.
Suitable for intermittent service up to 1499°F (815°C) and continuous service up to 1247°F (675°C), making it well-suited for high-temperature environments.
409 stainless steel is highly weldable. Preheating the material to 500°F (260°C) and annealing at 1499°F (815°C) after welding enhances the ductility of the weld, ensuring strong and reliable joints.
Grade 409 is a versatile stainless steel suitable for various applications that require corrosion resistance and moderate heat resistance.
409 stainless steel provides a cost-effective alternative to higher-priced stainless steel grades, making it a popular choice in many industries.
While slight surface rust may form over time, it does not impact the overall performance of the tube. However, the surface may be less aesthetically appealing compared to some other stainless steel grades.
Choose 409 stainless steel welded tube for its corrosion resistance, heat resistance, weldability, and cost-effectiveness. It is a reliable option for applications in various industries, available from Huaxiao stainless steel tube suppliers.

- Corrosion Resistance: 316 stainless steel offers excellent corrosion resistance, especially in corrosive environments and against pitting and crevice corrosion. On the other hand, 409 stainless steel provides good corrosion resistance in atmospheric and exhaust gas conditions, but it is not as corrosion resistant as 316 stainless steel.
- Temperature Resistance: 316 stainless steel has better high-temperature resistance compared to 409 stainless steel. It can withstand higher temperatures without losing its mechanical properties.
The differences between 409 and 410 stainless steel welded tubes:
- Composition: 409 stainless steel is a ferritic stainless steel containing 10.5-11.75% chromium and no nickel, while 410 stainless steel is a martensitic stainless steel with higher chromium content (11.5-13.5%) and a small amount of nickel (0.75%).
- Hardness: 410 stainless steel is a hardened, high-strength steel that can be heat-treated to achieve high levels of hardness. In contrast, 409 stainless steel is not as hard or strong as 410 stainless steel.
- Corrosion Resistance: 409 stainless steel provides good corrosion resistance in atmospheric and exhaust gas conditions, while 410 stainless steel offers better corrosion resistance and can be hardened to resist corrosion in mildly corrosive environments.
The differences between 409 and 304 stainless steel welded tubes:
- Composition: 409 stainless steel is a ferritic stainless steel with lower chromium content (10.5-11.75%) and no nickel, while 304 stainless steel is an austenitic stainless steel with higher chromium content (18-20%) and nickel content (8-10.5%).
- Corrosion Resistance: 304 stainless steel offers excellent corrosion resistance in a wide range of environments, including corrosive chemicals and marine environments. 409 stainless steel provides good corrosion resistance in atmospheric and exhaust gas conditions but is not as corrosion resistant as 304 stainless steel.
