Walid Stainless, based in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality stainless steel products. Among their specialized offerings are Stainless Steel 348H Bars, designed for applications requiring exceptional high-temperature performance, corrosion resistance, and long-term durability. These bars are ideal for industrial, chemical, and power-generation applications where exposure to extreme temperatures and harsh environments is common. At Walid Stainless, every bar is manufactured with precision and undergoes strict quality control to ensure consistent reliability. Clients rely on 348H Bars for strong, heat-resistant, and long-lasting solutions in critical industrial and structural projects.
Stainless Steel 348H Bars are made from a high-alloy austenitic stainless steel containing approximately 20–21% chromium, 25–28% nickel, 1.5–2% titanium, and small amounts of carbon. Titanium stabilizes the alloy, preventing sensitization and enhancing high-temperature corrosion resistance. These bars offer excellent tensile strength, typically 550–700 MPa, and high hardness, ensuring durability and mechanical stability under thermal and mechanical stress. The alloy’s austenitic structure ensures excellent creep resistance, dimensional stability, and resistance to oxidation, making 348H Bars ideal for high-temperature and chemically aggressive environments.
