Welcome to Maduka Metals, your trusted partner for premium industrial supplies right here in Abuja. We specialize in providing high-quality Stainless Steel 347 Hex Bar and Rod, sourced to meet the demanding needs of Nigeria’s growing construction and manufacturing sectors. Our commitment is to deliver not just a product, but a reliable solution that ensures the strength and longevity of your projects, backed by our local expertise and dedication to customer satisfaction.
The strength of Stainless Steel 347 lies in its specific composition, which includes chromium and nickel stabilized with columbium. This clever addition gives the alloy exceptional resistance to intergranular corrosion, especially after exposure to high temperatures. In practical terms, this means the hex bars and rods boast impressive mechanical properties, including high tensile strength and excellent creep resistance, allowing them to perform reliably under stress and in challenging thermal environments.

SS 347 Hex Bars are widely used in aerospace, chemical processing, and power generation for applications requiring high-temperature resistance, corrosion resistance, and strength. They outperform other grades due to their niobium stabilization, preventing carbide precipitation and ensuring durability.
SS 347 Hex Bars typically exhibit a tensile strength of 515-750 MPa, a yield strength of 205 MPa, and an elongation of 40% minimum. These properties ensure high durability, flexibility, and performance in demanding applications.
SS 347 Hex Bars commonly comply with standards like ASTM A276, ASTM A479, ASME SA479, and AMS 5646. These certifications ensure quality, dimensional accuracy, and performance for high-temperature and corrosion-resistant applications across industries, meeting stringent safety and reliability requirements.
This unique combination of properties makes Stainless Steel 347 hex bars and rods incredibly versatile. They are a preferred choice for fabricating components in high-temperature applications like furnace parts, jet engine manifolds, and boiler components. Beyond heat-intensive industries, they are also ideal for welding fixtures, structural supports in corrosive environments, and various fasteners within the chemical and petrochemical sectors, ensuring durability and safety where it matters most.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
