Samia Pipes and Tubes, based in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality industrial pipes and tubes. Among our specialized offerings are Stainless Steel 439 Pipes, engineered for excellent corrosion resistance, durability, and high-temperature performance. These ferritic stainless steel pipes are designed to provide reliable service in demanding environments, ensuring long-term efficiency and safety. At Samia Pipes and Tubes, we go beyond supplying materials—we deliver dependable solutions that support industrial operations. Every Stainless Steel 439 Pipe reflects our commitment to quality, precision, and lasting performance.
Stainless Steel 439 Pipes mainly consist of 17–19% chromium, featuring a very low carbon content (≤0.03%) to boost corrosion resistance and weldability, along with small amounts of manganese, silicon, and phosphorus. In terms of mechanical properties, they provide tensile strength ranging from 450–550 MPa and yield strength around 200–300 MPa, along with good elongation and toughness. These pipes excel in resisting high-temperature oxidation, scaling, and stress corrosion cracking. Additionally, Stainless Steel 439 Pipes offer solid formability, weldability, and durability, making them perfect for moderately corrosive environments and high-temperature industrial uses.
