Welcome to Tariku Metals, your trusted partner in Addis Ababa for premium stainless steel solutions. We take pride in manufacturing and supplying high-grade materials like our Stainless Steel 321H Square Bars and Rods, designed to meet the rigorous demands of Ethiopia’s growing industrial sector. Our commitment is to provide local engineers and fabricators with reliable, durable products that ensure the integrity and longevity of your most critical projects, backed by our deep understanding of the regional market and its unique challenges.
The strength of our 321H grade lies in its specialized composition, which includes chromium, nickel, and a carefully controlled addition of titanium. This formulation provides exceptional resistance to intergranular corrosion, particularly after exposure to high temperatures. The “H” designation indicates a higher carbon content, which gives these square bars and rods superior mechanical strength and creep resistance at elevated temperatures, making them a robust choice for demanding thermal environments.
