Mo3.3-V1.3-Cr8-Co5 Tool Steel

metal

This is a high-carbon, high-speed tool steel (HCHS) heavily alloyed with molybdenum, vanadium, and chromium, plus cobalt for elevated-temperature strength—a composition family derived from ASTM M-series tool steels optimized for extreme cutting and forming applications. It is used in precision metalworking for high-speed cutting tools, die-casting dies, and stamping tools where sustained thermal shock, abrasive wear, and edge retention under high-speed operation are critical demands. Engineers select this alloy when conventional tool steels cannot maintain hardness at elevated tool temperatures or when tool life cost justifies the material premium; the cobalt addition and high molybdenum content provide superior heat resistance and toughness compared to standard M2 or M4 tool steels.

Quality & Standards

Industry-Specific

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.
