409

409 Stainless Steel ERW pipes are made of an iron-based alloy that contains at least 10.5% chromium content, which provides excellent corrosion resistance. Adding other elements, such as titanium, aluminium, and molybdenum, enhances the mechanical properties of the steel. The typical chemical composition of Stainless Steel 409 ERW pipes includes 10.5-11.75% chromium, 0.08% carbon, 1.0% manganese, 0.5% nickel, 0.04% phosphorus, 0.03% sulfur, 0.75% silicon, 0.50% molybdenum, and 0.25% titanium. The combination of these elements creates a cost-effective material that can be used in a variety of applications. The low carbon content of these pipes makes them easy to fabricate and weld, providing good formability and ductility.

Stainless Steel 409 ERW Pipes are widely used in various industrial applications due to their exceptional resistance to high-temperature corrosion and ease of fabrication. The high chromium and low nickel content of SS 409 make it an economical alternative to other stainless steel grades while still providing good corrosion resistance. The pipes possess excellent formability and weldability, allowing easy fabrication and installation. In addition, they offer high strength, good oxidation resistance, and a smooth surface finish. These features make SS 409 ERW pipes suitable for use in many applications, particularly in the automotive industry for exhaust systems. With its cost-effective solution, SS 409 ERW pipes are a popular choice for many industries.
