Based in Addis Ababa, Tariku Metals stands as your trusted local partner for the highest quality industrial materials. We are proud manufacturers and suppliers specializing in high-performance alloys, with a focus on Super Duplex Steel 2507 bars and rods. Our commitment is to provide Ethiopian industries with robust solutions that withstand the most challenging environments. We understand that your projects demand reliability, which is why we ensure our products meet stringent international standards, supporting the growth and durability of critical infrastructure and manufacturing right here in our region.
The exceptional strength of Super Duplex Steel 2507 comes from its balanced composition, which includes significant amounts of chromium, nickel, molybdenum, and nitrogen. This synergy gives the material a two-phase microstructure, making it far stronger than standard stainless steels. It boasts an impressive tensile strength and excellent resistance to stress corrosion cracking, even under high pressures. This combination of rugged durability and inherent toughness makes these bars and rods a solid, long-lasting choice for heavy-duty applications where failure is not an option.

Yes, Super Duplex Steel 2507 bars can be welded, but they require proper welding techniques and precautions to avoid issues like thermal distortion and cracking. It is recommended to use skilled welders and specific filler materials.
Super Duplex Steel 2507 bars provide excellent corrosion resistance, high strength, and resistance to pitting, crevice, and stress corrosion cracking, making them ideal for harsh environments.
Yes, Super Duplex Steel 2507 Bars can be used for underground applications due to their excellent corrosion resistance, high strength, and durability in harsh environments. They are suitable for piping, structural, and reinforcement applications in underground settings.
Super Duplex Steel 2507 bars and rods are essential in sectors where both strength and corrosion resistance are paramount. You’ll find them at the heart of demanding applications like offshore oil and gas platforms, chemical processing plants, and pollution control systems. They are perfectly suited for components like pump shafts, fasteners, and valve stems that operate in harsh, chloride-rich environments. For projects in Ethiopia, from geothermal energy development to industrial chemical processing, these materials offer the resilience needed to ensure system integrity and longevity, minimizing maintenance and downtime.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
