Mourad Metals, located in Tunis, Tunisia, stands out as a top-notch manufacturer and supplier of premium stainless steel products, particularly known for their high-quality 303 bars and rods. With a strong reputation for precision, durability, and excellence, Mourad Metals serves a variety of industrial sectors that need reliable and corrosion-resistant materials. Their 303 stainless steel bars and rods are crafted under strict quality standards, guaranteeing consistent performance and precise dimensions. Committed to customer satisfaction, Mourad Metals offers customized solutions for engineering, automotive, and machinery applications, establishing itself as a trusted partner for both local and international clients in search of robust stainless steel options.
The 303 stainless steel bars and rods are mainly made up of iron, with 17–19% chromium, 8–10% nickel, and 0.15–0.35% sulfur to boost machinability. This alloy is known for its excellent corrosion resistance in both atmospheric and mildly corrosive settings. In terms of mechanical properties, it boasts a tensile strength of around 580–750 MPa, yield strength of 250–450 MPa, and an elongation of 20–25%, striking a great balance between strength and ductility. The inclusion of sulfur enhances machinability without significantly affecting toughness, making it perfect for precision components that need intricate machining and reliable dimensional stability under moderate stress.
