Walid Stainless, based in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their offerings are Stainless Steel 321H 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 assemblies exposed to extreme heat and oxidizing conditions. Each bar is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 321H Bars for reliable, long-lasting structural and mechanical solutions in demanding high-temperature and industrial applications.
Stainless Steel 321H Bars are made from a titanium-stabilized austenitic stainless steel alloy containing approximately 17–19% chromium, 9–13% nickel, and a higher carbon content (0.04–0.10%) than standard 321 for improved high-temperature strength. Titanium stabilization prevents sensitization and enhances corrosion resistance during thermal service. These bars typically exhibit tensile strength between 600–750 MPa and hardness around 180–220 HB. The austenitic structure ensures excellent creep resistance, dimensional stability, and mechanical durability under elevated temperatures, making 321H Bars suitable for high-temperature, chemical, and industrial applications.
