Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel fasteners. Their Stainless Steel 317 Bolts are engineered for exceptional corrosion resistance, particularly in chemical, marine, and chloride-rich environments. With added molybdenum, these bolts resist pitting, crevice corrosion, and general chemical attack while maintaining excellent mechanical strength. Manufactured under strict quality control, Walid Stainless ensures precise threading, smooth finishes, and consistent performance. Customers rely on Stainless Steel 317 Bolts for secure, durable, and long-lasting fastening in industrial plants, chemical processing units, and marine systems.
Stainless Steel 317 Bolts are made from an austenitic stainless steel alloy containing approximately 18–20% chromium, 11–15% nickel, and 3–4% molybdenum. The alloy provides superior resistance to pitting, crevice corrosion, and chemical attack. These bolts typically exhibit tensile strength between 515–620 MPa and hardness around 150–190 HB. Their austenitic structure ensures excellent toughness, corrosion resistance, and dimensional stability, making them suitable for demanding chemical, industrial, and marine applications requiring high-strength and reliable fastening.
