Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel tubing for demanding industrial and chemical environments. Their Stainless Steel 316L Tubing is designed for applications that require superior corrosion resistance, especially in chloride-rich and acidic conditions. With low carbon content, it minimizes intergranular corrosion and offers excellent weldability. Produced with precision and strict quality control, Walid Stainless ensures consistent dimensions, smooth finishes, and reliable mechanical performance. Customers rely on Stainless Steel 316L Tubing for durability, long service life, and dependable performance in harsh chemical, marine, and industrial applications.
Stainless Steel 316L Tubing is an austenitic stainless steel alloy containing approximately 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, with low carbon content for improved corrosion resistance. This composition enhances resistance to pitting, crevice corrosion, and chemical attack. The tubing typically exhibits tensile strength between 515–620 MPa and hardness around 150–190 HB. Its austenitic structure ensures excellent toughness, weldability, and dimensional stability, making it suitable for continuous exposure to aggressive industrial and marine environments.
