Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of high-quality stainless steel products. Among their specialized offerings are Stainless Steel 436 Nuts, designed for applications requiring excellent corrosion resistance, mechanical strength, and long-term durability. These nuts are ideal for industrial, mechanical, and structural assemblies exposed to moderately corrosive and high-temperature environments. At Walid Stainless, every nut is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 436 Nuts for secure, reliable, and long-lasting fastening solutions, making them a dependable choice for demanding industrial and mechanical projects.
Stainless Steel 436 Nuts are made from a high-chromium martensitic stainless steel alloy containing approximately 17–18% chromium and small amounts of nickel and carbon. This composition provides excellent corrosion resistance, mechanical strength, and hardness. These nuts typically exhibit tensile strength between 700–850 MPa and hardness around 200–240 HB. The martensitic structure ensures wear resistance, dimensional stability, and mechanical durability under moderate stress and corrosive conditions. 436 Nuts are suitable for industrial, mechanical, and automotive fastening applications requiring long-term reliability, strength, and moderate corrosion resistance.
