Mo3.4-V0.6-Cr8-Co5 Tool Steel
metalThis is a high-speed steel (HSS) variant optimized for extreme cutting and forming operations, distinguished by its high molybdenum and vanadium content combined with significant cobalt addition. Commonly found in precision cutting tools—end mills, drills, reamers, and broaches—where it delivers superior hot hardness and wear resistance compared to standard M-series high-speed steels. The cobalt boost enhances red hardness (strength retention at elevated temperatures), making it the choice for aggressive machining of cast iron, stainless steel, and aerospace alloys where tool life and cutting speed are critical cost drivers.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
