Walid Stainless, headquartered in Tunis, Tunisia, is a reliable manufacturer and supplier of premium stainless steel products for global industries. Their Stainless Steel 317L Pipes are specially designed for applications that demand superior corrosion resistance, strength, and long-term performance. Known for their higher molybdenum content, these pipes perform exceptionally well in aggressive chemical and marine environments. Every pipe is produced with precision engineering and strict quality checks to ensure consistency and durability. Customers trust Walid Stainless for 317L Pipes that deliver dependable performance, smooth flow characteristics, and long service life in demanding industrial conditions.
Stainless Steel 317L Pipes are manufactured from a low-carbon austenitic stainless steel alloy containing approximately 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. The higher molybdenum content significantly improves resistance to pitting and crevice corrosion, while low carbon reduces intergranular corrosion. These pipes typically exhibit tensile strength between 515–690 MPa and hardness around 170–200 HB. The austenitic structure ensures excellent toughness, weldability, and mechanical stability, making 317L Pipes suitable for demanding corrosive and high-pressure environments.
