Walid Stainless, based in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their specialized offerings are Stainless Steel 443 Pipes, engineered for applications requiring excellent corrosion resistance, durability, and stability in harsh environments. Known for their performance under elevated temperatures and challenging industrial conditions, these pipes are ideal for chemical, petrochemical, and structural applications. At Walid Stainless, every pipe is crafted with precision and undergoes rigorous quality control to ensure consistent reliability. Clients rely on 443 Pipes for safe, durable, and long-lasting piping solutions in demanding projects.
Stainless Steel 443 Pipes are made from a ferritic stainless steel alloy containing approximately 17–19% chromium. This composition provides excellent corrosion resistance, oxidation resistance, and thermal stability, while the low carbon content ensures dimensional stability. The pipes have moderate tensile strength, typically ranging from 450–600 MPa, and hardness around 170–200 HB. Their ferritic structure ensures wear resistance, durability, and reliability under mechanical and thermal stress. This makes 443 Pipes suitable for industrial, chemical, and high-temperature applications where consistent performance and long-term stability are essential.
