Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of premium stainless steel products. Among their specialized offerings are Stainless Steel 348 Pipes, designed for applications requiring high corrosion resistance, exceptional high-temperature strength, and long-term durability. These pipes are ideal for industrial, chemical, and power-generation systems exposed to extreme heat and aggressive environments. At Walid Stainless, every pipe is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 348 Pipes for safe, reliable, and long-lasting fluid transport and structural solutions in demanding industrial applications.
Stainless Steel 348 Pipes are made from a titanium-stabilized austenitic stainless steel alloy containing approximately 20–21% chromium, 25–28% nickel, and 1.5–2% titanium. Titanium stabilization prevents sensitization and enhances corrosion resistance at elevated temperatures. These pipes typically exhibit tensile strength between 550–700 MPa and hardness around 180–220 HB. The austenitic structure ensures excellent creep resistance, dimensional stability, and resistance to oxidation and scaling. 348 Pipes are suitable for high-temperature, chemically aggressive, and demanding industrial applications where long-term durability and performance are essential.
