Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their offerings are Stainless Steel 201 Nuts, designed for applications requiring good corrosion resistance, durability, and cost-effective performance. These nuts are ideal for automotive components, kitchen equipment, structural assemblies, and light industrial applications exposed to mildly corrosive environments. Each nut is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 201 Nuts from Walid Stainless for secure, reliable, and long-lasting fastening solutions in industrial, mechanical, and domestic applications.
Stainless Steel 201 Nuts are made from an austenitic stainless steel alloy containing approximately 16–18% chromium, 3.5–5.5% nickel, and 5–7% manganese. This composition provides good corrosion resistance, high tensile strength, and excellent mechanical properties at a lower cost than standard 304 stainless steel. These nuts typically exhibit tensile strength between 600–750 MPa and hardness around 160–200 HB. The austenitic structure ensures toughness, mechanical durability, and dimensional stability under stress. 201 Nuts are suitable for industrial, automotive, domestic, and mildly corrosive applications requiring strength, corrosion resistance, and cost efficiency.
