Tariku Metals, located in Addis Ababa, Ethiopia, has built a solid reputation as a reliable manufacturer and supplier of top-notch Tool and Die Steel O1 Bars. Known for their commitment to quality, precision, and customer satisfaction, the company produces steel that meets international performance standards. The O1 Bars from Tariku Metals are crafted with care using advanced manufacturing processes, ensuring consistent hardness, outstanding wear resistance, and remarkable dimensional stability. These bars are designed for both small-scale and industrial tooling applications, providing dependable performance that engineers, toolmakers, and manufacturers can count on for durable, high-quality steel solutions for precision tools and dies.
The Tool and Die Steel O1 Bars from Tariku Metals are oil-hardening, general-purpose cold work tool steels made up of carbon (0.85–1.00%), manganese (1.0–1.40%), chromium (0.40–0.60%), tungsten (0.50%), and vanadium (0.20–0.30%). This well-balanced composition results in a blend of toughness, high hardness, and excellent wear resistance. After heat treatment, O1 steel typically reaches a hardness of 57–62 HRC, offering good dimensional stability and machinability. It’s perfect for applications that require precise, stable tools with consistent edge retention and resistance to deformation under moderate working conditions.

When choosing O1 tool and die steel bars, consider factors like hardness, wear resistance, machinability, heat treatment requirements, intended application (e.g., cutting, stamping), and cost-effectiveness for long-term use.
O1 tool and die steel bars have moderate resistance to corrosion due to their carbon content and alloy composition. However, they are not stainless and can rust without proper maintenance, such as coating or regular oiling.
Tariku Metals’ Tool and Die Steel O1 Bars find their place in a wide range of industrial and tooling applications. They are perfect for crafting cutting tools, punches, dies, reamers, gauges, knives, and forming tools. Additionally, O1 Bars are utilized in molds, woodworking tools, and cold working dies that require both precision and strength. Their oil-hardening feature helps reduce distortion during heat treatment, ensuring dimensional accuracy. With a great mix of wear resistance and machinability, Tariku Metals’ O1 Bars promise reliable, long-lasting performance in both production and maintenance tool manufacturing.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
