Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of premium stainless steel products. Among their specialized offerings are Stainless Steel 347 Bars, designed for applications requiring excellent high-temperature strength, corrosion resistance, and long-term durability. These bars are ideal for industrial, chemical, and power-generation equipment exposed to elevated temperatures and harsh environments. At Walid Stainless, each bar is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 347 Bars for reliable, heat-resistant, and long-lasting solutions, making them a preferred choice for demanding industrial and structural projects.
Stainless Steel 347 Bars are made from a titanium-stabilized austenitic stainless steel alloy containing approximately 17–19% chromium, 9–13% nickel, and low carbon content. Titanium stabilization prevents sensitization and enhances corrosion resistance, particularly at elevated temperatures. These bars 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. 347 Bars are suitable for high-temperature, chemically aggressive, and demanding industrial applications requiring long-term reliability and resistance to oxidation.
