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 440C Nuts, designed for applications requiring superior hardness, wear resistance, and corrosion protection. These nuts are ideal for industrial, mechanical, and precision assemblies where durability and reliability are critical. At Walid Stainless, each nut is manufactured with precision and undergoes rigorous quality control to ensure consistent performance. Clients rely on 440C Nuts for secure, long-lasting fastening solutions, making them a dependable choice for demanding industrial, mechanical, and high-performance projects.
Stainless Steel 440C Nuts are made from a high-carbon martensitic stainless steel alloy containing approximately 16–18% chromium. This composition provides excellent hardness, wear resistance, and moderate corrosion resistance. The alloy is heat-treatable, typically achieving tensile strength of 750–950 MPa and hardness up to 60 HRC. The martensitic structure ensures dimensional stability, mechanical durability, and resistance to wear under high stress. 440C Nuts are suitable for industrial, automotive, and precision mechanical fastening applications where maximum hardness, strength, and long-term performance are required.
