Maduka Metals, a trusted manufacturer and supplier located in Abuja, Nigeria, specializes in top-notch Stainless Steel 420 Hex Bars that are built for outstanding strength, durability, and resistance to corrosion. These bars are crafted to meet international standards, guaranteeing reliable performance in various industrial applications. Renowned for their impressive hardness and smooth, polishable surface, Stainless Steel 420 Hex Bars find extensive use in engineering, mechanical, and tooling industries. Maduka Metals is dedicated to providing precision-engineered products that excel in wear resistance, machinability, and overall performance, whether in moderate or challenging environments.
The composition of Stainless Steel 420 Hex Bars primarily includes iron, chromium (12–14%), carbon (0.15–0.40%), along with trace amounts of manganese and silicon. This type of martensitic stainless steel is known for its high tensile strength, hardness, and decent corrosion resistance, especially when it has been hardened and tempered. Its mechanical properties boast a tensile strength ranging from about 700 to 1000 MPa, along with good impact resistance. The alloy can undergo heat treatment to enhance its wear resistance and edge retention while ensuring it remains dimensionally stable and easy to machine.

The Hex Bar shape offers improved grip, stability, and easier alignment during machining or fabrication. It reduces rotation and slippage, allowing for more accurate cuts and efficient handling, especially when working with the hard, durable SS 420 stainless steel.
SS 420 Hex Bars are commonly used in applications requiring high wear resistance, such as shafts, valves, and tools. Its ability to be heat-treated for superior hardness and strength makes it ideal for demanding environments compared to other stainless steel grades.
Industries such as automotive, aerospace, defense, and manufacturing frequently utilize Stainless Steel 420 Hex Bars. They are perfect for crafting surgical instruments, pump shafts, cutlery, molds, and machine parts that require a tough yet corrosion-resistant material. Thanks to their excellent polishability and ability to maintain a sharp edge, these bars are also popular in knife blades, valve components, and precision tools. Their remarkable strength, hardness, and durability make them ideal for applications that face friction, impact, and high-stress conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
