As a leading manufacturer and supplier based in the heart of Addis Ababa, Tariku Metals is proud to provide industry professionals with high-quality Stainless Steel 347H Square Bars and Rods. We understand the critical demands of modern fabrication and construction, which is why we ensure our materials are sourced and prepared to meet the most rigorous standards. Our commitment is to support Ethiopia’s growing infrastructure with reliable, durable stainless steel products that form the backbone of essential projects.
The strength of these bars comes from a carefully balanced composition, primarily chromium and nickel, with a key addition of niobium. This combination grants the steel exceptional resistance to intergranular corrosion, especially following exposure to high temperatures. Mechanically, it offers impressive tensile strength and excellent creep resistance, meaning it maintains its integrity and performance under sustained stress and heat, making it a robust choice for challenging environments.

Stainless Steel 347H Square Bars offer excellent high-temperature strength, resistance to intergranular corrosion, and superior weldability. They are ideal for applications in extreme environments, such as chemical processing and heat exchangers.
Yes, Stainless Steel 347H Square Bars are fully recyclable and retain their properties after recycling. This makes them an environmentally sustainable choice for various applications.
No, Stainless Steel 347H Square Bars are generally non-magnetic in their annealed condition. However, slight magnetism may develop after cold working.
You will commonly find Stainless Steel 347H square bars and rods serving crucial roles in high-temperature applications. They are ideally suited for fabricating components in the petrochemical industry, such as refinery equipment and exhaust systems, as well as in power generation plants. Their stability also makes them a preferred material for welded assemblies, structural frames, and architectural elements where long-term durability against heat and corrosion is a non-negotiable requirement for project success.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
