Stainless Steel 409 EFW Pipes

409 Stainless Steel EFW 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 EFW 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 EFW Pipes are commonly used in various industrial applications such as automotive exhaust systems, heat exchangers, and furnaces due to their excellent 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 more expensive stainless steel grades while still offering good corrosion resistance. The pipes exhibit good formability and weldability, allowing for ease of fabrication and installation. In addition, they possess high strength, excellent resistance to oxidation, and a smooth surface finish, making them suitable for use in a wide range of applications. With its cost-effective solution, SS 409 EFW pipes are popular in many industries.
