Semih Metals, a well-known manufacturer and supplier located in Istanbul, Turkey, has made a name for itself globally by offering top-notch High Speed Steel T1 Bars to a variety of industries. These bars are celebrated for their durability, precision, and compliance with international standards, making them ideal for high-stress and high-speed cutting tasks. High Speed Steel T1 Bars are prized for their remarkable hardness, wear resistance, and their ability to maintain sharp cutting edges even in extreme heat. With a commitment to innovation, customer satisfaction, and prompt delivery, Semih Metals has established itself as a reliable partner for advanced tool steel solutions in markets around the world.
These High Speed Steel T1 Bars are made from tungsten-based steel, featuring about 18% tungsten, 4% chromium, 1% vanadium, and 0.7% carbon, which together provide outstanding hardness, toughness, and wear resistance. This unique composition allows them to maintain high red hardness, ensuring they stay efficient at elevated temperatures. After heat treatment, these bars boast a tensile strength of around 1,300 MPa and hardness values that exceed 63 HRC. With excellent edge retention, durability, and resistance to deformation under thermal stress, High Speed Steel T1 Bars are particularly well-suited for demanding machining and cutting tasks that require long-lasting performance.

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.
High Speed Steel T1 Bars are commonly used in the production of cutting tools like drills, taps, milling cutters, saw blades, and reamers, thanks to their impressive hardness and edge retention. They also find applications in gear cutting tools, cold work tasks, and precision machining operations where wear resistance and toughness are essential. Industries such as automotive, aerospace, and engineering depend on T1 Bars to create high-performance tools that can withstand extreme speeds and temperatures. Their exceptional durability, thermal stability, and wear resistance make High Speed Steel T1 Bars essential for industries that need reliable and long-lasting tooling solutions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
