Rashdan Pipes and Tubes, a trusted manufacturer and supplier in Amman, Jordan, provides high-quality Stainless Steel 304L EFW Pipes designed for industries that require durability, corrosion resistance, and weldability. The low-carbon 304L grade minimizes carbide precipitation during welding, making these EFW pipes ideal for high-integrity welded systems. Rashdan Pipes and Tubes combines precision engineering, rigorous quality control, and customer-focused service to ensure every product meets international standards. These pipes are reliable solutions for chemical, petrochemical, food processing, and water treatment industries, providing long-term performance, structural integrity, and safety in demanding applications.
Stainless Steel 304L EFW Pipes are an austenitic stainless steel alloy containing 18–20% chromium and 8–12% nickel, with low carbon content (≤0.03%) to prevent carbide precipitation and improve weldability. These pipes provide tensile strength of approximately 515 MPa and yield strength around 205 MPa, with excellent ductility and toughness. Their corrosion resistance remains strong in chemical, marine, and atmospheric environments. The combination of low carbon, balanced alloy composition, and stable austenitic microstructure ensures reliable high-temperature performance, weldability, and long-term structural integrity in demanding industrial applications.
