Walid Stainless, headquartered in Tunis, Tunisia, is a trusted manufacturer and supplier of premium stainless steel products. Among their specialized offerings are Stainless Steel 440C Stud Bolts, engineered for applications requiring high hardness, excellent wear resistance, and moderate corrosion resistance. These stud bolts are ideal for industrial machinery, precision equipment, and chemical processing assemblies where strength and durability are critical. Each stud bolt is manufactured with precision and undergoes strict quality control to ensure consistent performance. Clients rely on 440C Stud Bolts for secure, reliable, and long-lasting fastening solutions in demanding mechanical and industrial projects.
Stainless Steel 440C Stud Bolts are made from a high-carbon martensitic stainless steel alloy containing approximately 16–18% chromium and 0.95–1.2% carbon. This composition provides exceptional hardness, excellent wear resistance, and moderate corrosion resistance. These bolts typically exhibit tensile strength between 750–1,000 MPa and hardness ranging from 55–60 HRC. The martensitic structure ensures high mechanical durability, dimensional stability, and resistance to wear and fatigue. 440C Stud Bolts are suitable for industrial, mechanical, and high-stress fastening applications requiring long-term reliability and strength.
