Product Description of 409 Stainless Steel Welded Tube

Huaxiao Stainless Steel Tube Suppliers

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 304430, 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

Huaxiao Stainless Steel Tube Suppliers

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.
