Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-performance stainless steel fastening solutions. Their Stainless Steel 317L Bolts are engineered for applications that demand exceptional corrosion resistance and long-term reliability. With enhanced molybdenum content and low carbon composition, these bolts perform exceptionally well in aggressive chemical and marine environments. Manufactured with precision and strict quality control, Walid Stainless ensures consistent strength, accurate threading, and dependable performance. Customers rely on Stainless Steel 317L Bolts for secure fastening, durability, and confidence in critical industrial and structural applications.
Stainless Steel 317L Bolts are produced from an austenitic stainless steel alloy containing approximately 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with low carbon content. The higher molybdenum improves resistance to pitting and crevice corrosion. These bolts typically exhibit tensile strength between 515–620 MPa and hardness around 150–190 HB. The austenitic structure provides excellent toughness, weldability, and mechanical stability in corrosive and high-stress environments.
