Walid Stainless, headquartered in Tunis, Tunisia, is a reliable manufacturer and supplier of practical stainless steel tubing solutions for industrial and automotive applications. Their Stainless Steel 409 Tubing is designed for environments where moderate corrosion resistance, heat stability, and cost efficiency are key requirements. As a ferritic stainless steel grade, it offers good oxidation resistance at elevated temperatures and dependable mechanical performance. Manufactured with precision and strict quality control, Walid Stainless ensures consistent dimensions and durability. Customers rely on Stainless Steel 409 Tubing for reliable service in heat-exposed and structural applications.
Stainless Steel 409 Tubing is produced from a ferritic stainless steel alloy containing approximately 10.5–11.75% chromium, with small additions of titanium for stabilization. This composition provides good oxidation resistance and improved weldability. The tubing typically exhibits tensile strength between 380–500 MPa and hardness around 150–190 HB. The ferritic structure offers resistance to stress corrosion cracking, good thermal conductivity, and dimensional stability under moderate temperature conditions.
