Tariku Metals, based in Addis Ababa, Ethiopia, has earned a solid reputation as a reliable manufacturer and supplier of high-performance Tool and Die Steel S1 Bars. The company is well-known for its dedication to quality, precision, and ensuring customer satisfaction, consistently delivering steels that adhere to international standards for strength and durability. Utilizing advanced metallurgical processes, Tariku Metals produces S1 Bars that boast excellent shock resistance, toughness, and wear resistance. These bars are specifically designed for challenging industrial environments, making them perfect for tooling, forging, and impact applications, and they promise dependable, long-lasting performance across the manufacturing, engineering, and metalworking industries.
The Tool and Die Steel S1 Bars from Tariku Metals are made from tungsten-chromium shock-resisting tool steels, featuring a composition of carbon (0.50–0.60%), tungsten (1.75–2.25%), chromium (0.30–0.50%), and silicon (0.20–1.00%). This unique blend provides remarkable impact toughness, moderate wear resistance, and high strength even at elevated temperatures. After heat treatment, the steel achieves a hardness range of 56–58 HRC and maintains dimensional stability during use. Additionally, S1 steel showcases excellent machinability and resists softening under thermal stress, making it an ideal choice for tools that face severe impact and fatigue conditions.

When choosing Tool and Die Steel S1 bars, consider hardness, wear resistance, toughness, machinability, heat treatment capabilities, and the specific requirements of the application to ensure optimal performance and durability.
Tool and Die Steel S1 bars resist corrosion due to their alloy composition, which includes elements like chromium and molybdenum. These elements form a protective oxide layer, enhancing resistance to oxidation and rust.
Tariku Metals’ Tool and Die Steel S1 Bars are extensively utilized in applications that require outstanding impact resistance and durability. They are perfect for crafting cold chisels, punches, hammers, forging dies, and shear blades. Thanks to the steel’s toughness, it can endure repeated shock loads, making it suitable for both hot and cold work tooling. Moreover, S1 Bars find their place in riveting and heading dies, driver bits, and other heavy-duty tools that are regularly subjected to impact and stress. With their excellent mechanical balance and long service life, Tariku Metals’ S1 Bars guarantee reliable performance in high-impact industrial operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
