What is High Speed Steel M42 Bars ?

High Speed Steel M42 Bars are made mostly of iron, containing roughly 1.05% carbon, 8–10% cobalt, 4% chromium, 1.5% molybdenum, 1.5% vanadium, and 1% tungsten. This distinctive combination provides them with exceptional hardness, wear resistance, and red hardness, which makes them well suited for high-speed cutting operations. In terms of mechanical properties, M42 steel delivers a tensile strength of 1200–1500 MPa, hardness between 64 and 67 HRC, and remarkable toughness. The material retains its strength at elevated temperatures, demonstrates excellent fatigue resistance, and provides great machinability and grindability, making it a preferred choice for high-performance tooling applications.
