Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of premium stainless steel products. Among their specialized offerings are Stainless Steel 330 Pipes, designed for applications requiring exceptional high-temperature strength, corrosion resistance, 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, each pipe is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 330 Pipes for safe, reliable, and long-lasting fluid transport and structural solutions in demanding high-temperature industrial applications.
Stainless Steel 330 Pipes are made from a high-alloy austenitic stainless steel containing approximately 34% nickel, 28% chromium, and small amounts of copper and silicon. This composition provides outstanding resistance to oxidation, scaling, and corrosion 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 mechanical durability under thermal and mechanical stress. 330 Pipes are suitable for high-temperature, chemically aggressive, and demanding industrial applications requiring long-term performance.
