Walid Stainless is a reputable manufacturer and supplier located in Tunis, Tunisia, dedicated to delivering top-notch stainless steel products that cater to a wide range of industrial needs. They specialize in SS 418 Sheets and Plates, which are highly regarded for their strength, durability, and dependable performance in moderately corrosive environments. Thanks to their state-of-the-art manufacturing facilities, skilled workforce, and rigorous quality assurance processes, Walid Stainless guarantees that their products meet international standards. Their SS 418 Sheets and Plates find applications in engineering, construction, automotive, and industrial equipment sectors, ensuring consistent quality, precise dimensions, timely delivery, and reliable customer support for both local and global clients.
SS 418 Sheets and Plates are martensitic stainless steels, primarily composed of chromium and controlled carbon content. Typically, they contain about 11.5–14 percent chromium, which provides a balance of moderate corrosion resistance and good strength. Mechanically, SS 418 boasts high tensile strength, solid hardness, and reasonable toughness when properly heat-treated. These sheets and plates also demonstrate excellent wear resistance and maintain dimensional stability under stress. While they may have lower ductility compared to austenitic grades, SS 418 excels in applications that demand strength, machinability, and resistance to mild corrosion and oxidation.
