Welcome to Maduka Metals, your trusted partner for premium industrial materials right here in Abuja. We take pride in supplying high-grade stainless steel solutions tailored for Nigeria’s demanding environments. Our Stainless Steel 310S Hollow Bar is a standout product, specifically chosen for its exceptional ability to withstand intense heat and corrosion. It’s the reliable, durable choice for engineers and fabricators who need a material that performs consistently under pressure, ensuring the integrity and longevity of your most critical projects.
The strength of the 310S Hollow Bar comes from its unique composition, rich in chromium and nickel, which gives it outstanding resistance to oxidation and scaling. This alloy maintains its structural integrity even when exposed to temperatures up to 1100°C. Mechanically, it offers excellent tensile strength and good ductility, allowing it to be machined and welded into complex components without losing its robust, heat-resistant characteristics, making it a truly resilient material.

The high chromium (25%) and nickel (20%) content in SS 310S enhances its resistance to corrosion by forming a protective oxide layer on the surface. This layer shields the material from aggressive environmental factors, preventing oxidation and corrosion in harsh conditions.
SS 310S Hollow Bars are commonly used in industries such as power generation, chemical processing, petrochemical, aerospace, and manufacturing. They are essential for components in high-temperature environments, including furnace parts, heat exchangers, boilers, reactors, and gas turbines.
This hollow bar is indispensable in industries where high temperatures are a constant challenge. You’ll find it expertly fabricated into vital components for furnace parts, heat treatment fixtures, and industrial oven linings. It’s also the preferred material for exhaust systems, chemical processing equipment, and power generation applications. Its hollow design makes it ideal for creating lightweight yet strong tubular structures, fluid transfer systems, and custom machinery parts that must endure extreme thermal and corrosive conditions day in and day out.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
