Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel fasteners. Their Stainless Steel 317L Nuts are designed for applications that require exceptional corrosion resistance in aggressive chemical, marine, and industrial environments. With low carbon content and added molybdenum, these nuts resist pitting, crevice corrosion, and general chemical attack while maintaining excellent strength and durability. Manufactured under strict quality control, Walid Stainless ensures precise threading, smooth finishes, and reliable mechanical performance. Customers rely on 317L Nuts for long-term service, secure fastening, and dependable performance in critical applications.
Stainless Steel 317L Nuts are made from an austenitic stainless steel alloy containing approximately 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with low carbon content to minimize intergranular corrosion. This composition provides excellent resistance to pitting, crevice corrosion, and chemical exposure. The nuts typically exhibit tensile strength between 500–700 MPa and hardness around 150–190 HB. Their austenitic structure ensures superior toughness, corrosion resistance, and dimensional stability, making them ideal for demanding chemical, marine, and industrial applications.
