Located in the heart of Addis Ababa, Tariku Metals stands as a trusted partner for Ethiopia’s growing industrial sector. We are proud manufacturers and suppliers of precision-engineered High Speed Steel T42 Bars, providing local industries with the exceptional cutting tools needed to drive progress. By offering this superior-grade material, we empower Ethiopian workshops and factories with the reliability and performance required to compete on a global scale, ensuring that quality and durability are always within reach for our nation’s builders and innovators.
The composition of High Speed Steel T42 is a sophisticated blend that includes tungsten, molybdenum, cobalt, and vanadium. This specific alloy recipe gives the steel its renowned red-hardness, allowing it to maintain a sharp cutting edge even when it becomes red-hot from friction during high-speed operations. The result is a tool steel with exceptional wear resistance, high strength, and the ability to withstand significant thermal stress, making it a superior choice for demanding industrial cutting and machining tasks.

Yes, T42 Alloy High-Speed Steel Bars can be heat treated. They are typically hardened through heat treatment processes like quenching and tempering to enhance hardness, wear resistance, and performance.
Welding T42 High-Speed Steel Bars is challenging due to their high carbon content and hardness. If welding is required, preheating and post-weld heat treatment are often necessary to prevent cracking and ensure strength.
T42 High-Speed Steel Bars should be stored in a dry, cool environment to prevent rust and corrosion. They should be kept off the ground, ideally on wooden or plastic pallets, and protected from moisture and extreme temperatures.
The primary use for High Speed Steel T42 Bars is in the creation of high-performance cutting tools where failure is not an option. This includes manufacturing drill bits, end mills, reamers, and lathe tools that are essential for metalworking shops, automotive industries, and heavy machinery maintenance. Its ability to cut tough materials efficiently at high speeds makes it indispensable for operations requiring precision and longevity, directly contributing to increased productivity and reduced downtime in various manufacturing and engineering applications across Ethiopia.
