Mo3.4-V1.0-Cr7-Co5 Tool Steel (var. 2)
metalA high-carbon, high-alloy tool steel (variant 2) combining molybdenum, vanadium, chromium, and cobalt to deliver exceptional hardness, wear resistance, and heat resistance in demanding cutting and forming applications. This composition sits in the premium high-speed steel family, with cobalt addition (~5%) enhancing hot hardness and thermal fatigue resistance—critical for sustained high-temperature cutting operations. Engineers select this grade when tool life, thermal stability, and resistance to plastic deformation at elevated temperatures outweigh cost considerations, making it ideal for aggressive machining of difficult materials and extended production runs where tool replacement downtime is costly.
