Walid Stainless, based in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality stainless steel products. Among their premium offerings are Stainless Steel 439 Bars, engineered for applications that demand excellent corrosion resistance, durability, and strength. Known for their exceptional performance in harsh and high-temperature environments, these bars are ideal for industrial, structural, and mechanical applications. At Walid Stainless, every bar is crafted with precision and undergoes stringent quality control to ensure consistent reliability. Clients rely on 439 Bars for long-lasting performance, safety, and stability, making them a dependable choice for critical projects.
Stainless Steel 439 Bars are made from a ferritic stainless steel alloy with approximately 17–18% chromium, offering excellent resistance to corrosion, oxidation, and stress corrosion cracking. The low-carbon content ensures dimensional stability, while the alloy’s ferritic structure provides moderate strength and good thermal conductivity. These bars typically feature tensile strength of 450–600 MPa and hardness around 170–200 HB. Their composition ensures durability, wear resistance, and reliability in industrial and structural applications, making them ideal for components exposed to harsh environmental or high-temperature conditions.
