Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel tubing for industrial and chemical applications. Their Stainless Steel 317 Tubing is specially designed for environments requiring superior corrosion resistance, particularly in chloride-rich and acidic conditions. With higher molybdenum content than standard 316, it offers enhanced resistance to pitting and crevice corrosion. Manufactured with precision and strict quality control, Walid Stainless ensures consistent dimensions, smooth finishes, and reliable mechanical performance. Customers rely on Stainless Steel 317 Tubing for durability, long service life, and dependable operation in aggressive industrial environments.
Stainless Steel 317 Tubing is an austenitic stainless steel alloy containing approximately 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. The high molybdenum content improves resistance to pitting and crevice corrosion in aggressive chemical environments. This tubing typically exhibits tensile strength between 515–620 MPa and hardness around 150–190 HB. Its austenitic structure provides excellent toughness, corrosion resistance, and dimensional stability, making it suitable for continuous exposure to harsh industrial and chemical conditions.
