Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their offerings are Stainless Steel 321 Bars, engineered for applications requiring excellent corrosion resistance, high-temperature stability, and durability. These bars are ideal for industrial, chemical, and power-generation assemblies exposed to elevated temperatures and oxidizing environments. Each bar is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 321 Bars for reliable, long-lasting structural and mechanical solutions in demanding industrial, chemical, and high-temperature applications.
Stainless Steel 321 Bars are made from a titanium-stabilized austenitic stainless steel alloy containing approximately 17–19% chromium, 9–13% nickel, and small amounts of carbon and titanium. Titanium stabilization prevents sensitization and improves corrosion resistance during high-temperature service. These bars typically exhibit tensile strength between 550–700 MPa and hardness around 180–220 HB. The austenitic structure provides excellent mechanical durability, dimensional stability, and resistance to creep and oxidation under high temperatures. 321 Bars are suitable for chemical, industrial, and high-temperature applications requiring strength, corrosion resistance, and long-term reliability.
