Walid Stainless, based in Tunis, Tunisia, is a leading manufacturer and supplier of premium stainless steel products. Among their specialized offerings are Stainless Steel 347H 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 environments. At Walid Stainless, each bar is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 347H Bars for reliable, heat-resistant, and long-lasting solutions, making them a preferred choice for demanding high-temperature industrial and structural projects.
Stainless Steel 347H Bars are made from a titanium-stabilized austenitic stainless steel alloy containing approximately 17–19% chromium, 9–13% nickel, and 0.04–0.10% carbon. Titanium stabilizes the alloy, preventing sensitization and enhancing corrosion resistance, especially at elevated temperatures. These bars typically have tensile strength between 550–700 MPa and hardness around 180–220 HB. The austenitic structure provides excellent creep resistance, dimensional stability, and oxidation resistance, making 347H Bars suitable for high-temperature, chemically aggressive, and demanding industrial applications.
