Cutting tools made of High-Speed Steel (HSS) achieve high hot hardness, wear resistance and fracture resistance at a hardness of over 60 to 67 HRC through hardening and tempering. The main alloying elements are Carbon, Tungsten, Molybdenum, Vanadium, Cobalt and Chromium. The high contents of carbide-forming elements lead to the formation of wear-resistant carbides in the microstructure of HSS.
High‑Speed Steels are engineered for the most demanding metal cutting applications -including drilling, milling, threading, broaching, gear cutting, reaming as well as cold work tooling and precision manufacturing – where consistent quality, long tool life, wear resistance, hot hardness, and toughness are essential. Combining advanced alloy design through powder metallurgical technology (PM), these steels deliver high edge retention, thermal stability above 600 °C and outstanding fracture resistance.
Premium PM grades known as BÖHLER MICROCLEAN offer exceptional carbide uniformity, ensuring longer tool life, fewer tool changes, and highly reproducible tool performance. It makes BÖHLER High‑Speed Steel grades the preferred choice for industrial cutting tools, automotive tooling, consumer goods tooling, and precision cold‑forming applications. The extensive portfolio enables tailored solutions for demanding cutting tools applications, while value‑adding services -heat treatment, and PVD coatings further optimize tool performance. Developed and produced in the specialized BÖHLER plant located in Kapfenberg, Austria ,these HSS materials provide the reliability, durability and productivity required for modern high‑precision manufacturing.
