Walid Stainless, based in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality stainless steel products. Among their premium offerings are Stainless Steel 348 Bars, engineered for applications requiring exceptional high-temperature strength, corrosion resistance, and long-term durability. These bars are ideal for industrial, chemical, and power-generation equipment exposed to extreme heat and harsh operating conditions. At Walid Stainless, every bar is produced with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 348 Bars for dependable, heat-resistant, and long-lasting solutions in critical industrial and structural projects.
Stainless Steel 348 Bars are made from a high-alloy austenitic stainless steel containing approximately 20–21% chromium, 25–28% nickel, 1.5–2% titanium, and low carbon content. Titanium stabilizes the alloy, preventing sensitization and enhancing high-temperature corrosion resistance. These bars exhibit tensile strength between 550–700 MPa and excellent hardness, offering durability and mechanical stability under thermal and mechanical stress. The austenitic structure ensures exceptional creep resistance, dimensional stability, and oxidation resistance, making 348 Bars suitable for high-temperature, chemically aggressive, and demanding industrial environments.
