From the heart of Addis Ababa, Tariku Metals stands as a dedicated partner to Ethiopia’s growing industrial landscape. We take pride in manufacturing and supplying the most critical components for demanding applications, starting with our premium High-Speed Steel T1 Bars. Known for unwavering quality and reliability, our T1 bars are the cornerstone for tools that must perform under extreme pressure, helping local industries achieve greater precision and efficiency in their most challenging tasks.
The strength of our T1 bars comes from a carefully balanced composition, primarily tungsten (18%), chromium (4%), and vanadium (1%). This specific alloy recipe gives the steel its signature ability to retain a sharp cutting edge even when it gets red-hot during high-speed operations. It achieves an impressive balance of high hardness and exceptional wear resistance, ensuring that tools made from our material don’t just cut well initially but continue to perform reliably over a long service life.

Yes, High-Speed Steel T1 bars can be welded, but it requires specialized techniques like preheating and post-weld heat treatment to prevent cracking and maintain their hardness and strength properties.
High-Speed Steel T1 bars resist corrosion due to the presence of chromium, which forms a protective oxide layer on the surface. This enhances their resistance to moisture and chemical wear, prolonging tool life.
You’ll find tools made from our T1 bars at work in some of the most demanding environments. They are the preferred material for manufacturing a wide range of cutting tools, including drill bits, milling cutters, lathe tools, and saw blades. Beyond metalworking, these bars are essential for creating durable woodworking tools and specialized blades for the food processing and packaging industries. Essentially, any application where a tool must cut quickly, accurately, and for a long time without failing is a perfect match for the superior performance of Tariku’s T1 steel.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Tariku Metals is a leading manufacturer, supplier, and exporter of high-quality bars, rods, and forgings, catering to various industries in Addis Ababa, Ethiopia
