Walid Stainless, headquartered in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality stainless steel products. Among their specialized offerings are Stainless Steel 418 Bars, designed for applications requiring strong corrosion resistance, excellent mechanical strength, and long-term durability. These bars are ideal for industrial, structural, and mechanical projects exposed to moderately corrosive or high-temperature environments. At Walid Stainless, each bar is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 418 Bars for reliable, long-lasting, and high-performing solutions, making them a preferred choice for demanding industrial and mechanical applications.
Stainless Steel 418 Bars are made from a martensitic stainless steel alloy containing approximately 13–14% chromium, with small amounts of titanium for stabilization. This composition provides good corrosion resistance, high hardness, and excellent mechanical strength. The bars typically exhibit tensile strength between 650–800 MPa and hardness around 200–240 HB. The martensitic structure ensures wear resistance, dimensional stability, and mechanical durability. 418 Bars are ideal for applications requiring reliable long-term performance, moderate corrosion resistance, and the ability to withstand mechanical and thermal stress.
