Maduka Metals, located in Abuja, Nigeria, is your go-to source for top-notch Stainless Steel 420 Square Bars and Rods. We take pride in crafting our products with precision to meet international standards, ensuring they offer exceptional strength, durability, and resistance to corrosion. Stainless Steel 420 is particularly valued for its high carbon content and impressive hardenability, making it perfect for applications that require both wear resistance and a polished finish. At Maduka Metals, we’re dedicated to meeting a variety of industrial needs, with a strong focus on quality, timely delivery, and customer satisfaction. This commitment has made us a preferred choice for stainless steel solutions not just in Nigeria, but beyond.
Our Stainless Steel 420 Square Bars and Rods are martensitic stainless steels, primarily made up of chromium (12–14%), carbon (at least 0.15%), along with manganese, silicon, phosphorus, and sulfur. This unique blend allows the alloy to achieve remarkable hardness after heat treatment. In terms of mechanical properties, it boasts high tensile strength, good toughness, and moderate resistance to corrosion. These bars can be polished to a brilliant finish while maintaining their mechanical integrity even under high stress. They also offer good machinability and can be hardened to maximize strength and wear resistance for demanding engineering applications.
