Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-performance stainless steel fastening solutions. Their Stainless Steel 317 Nuts are engineered for applications that demand superior corrosion resistance and mechanical reliability. With a higher molybdenum content, these nuts perform exceptionally well in aggressive chemical and chloride-rich environments. Manufactured using precision-controlled processes and strict quality inspections, Walid Stainless ensures accurate threading, consistent strength, and long service life. Customers rely on Stainless Steel 317 Nuts for secure fastening, durability, and dependable performance in critical industrial assemblies.
Stainless Steel 317 Nuts are produced from an 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. These nuts typically exhibit tensile strength comparable to 317-grade fasteners and hardness around 150–190 HB. The austenitic structure ensures excellent toughness, corrosion resistance, and stable mechanical performance under stress and varying temperatures.
