Walid Stainless, based in Tunis, Tunisia, is a leading manufacturer and supplier of premium stainless steel products. Among their offerings are Stainless Steel 317L Bars, engineered for applications requiring superior corrosion resistance in highly aggressive environments. These bars are ideal for industrial, chemical, and marine assemblies where durability and long-term reliability are essential. Each bar is manufactured with precision and undergoes strict quality control to ensure consistent quality. Clients rely on 317L Bars for safe, dependable performance in demanding chemical and industrial applications, making them a preferred choice for engineers and fabricators worldwide.
Stainless Steel 317L Bars are made from a low-carbon austenitic stainless steel alloy containing approximately 18% chromium, 13% nickel, and 4% molybdenum. The reduced carbon content minimizes carbide precipitation, enhancing resistance to intergranular corrosion. These bars typically exhibit tensile strength between 550–700 MPa and hardness around 170–210 HB. The austenitic structure ensures mechanical durability, excellent toughness, and dimensional stability under thermal and mechanical stress. 317L Bars are suitable for chemical, marine, and industrial applications where high corrosion resistance and long-term reliability are critical.
