Mo3.3-V1.1-Cr8-Co5 Tool Steel

metal

This is a high-carbon, high-speed tool steel (HSST) formulation with elevated molybdenum, vanadium, chromium, and cobalt additions designed for extreme hardness and heat resistance in metal-cutting applications. The alloy's composition—particularly the 2% carbon, 3.3% molybdenum, and 1.1% vanadium with cobalt enhancement—targets cutting tool performance where thermal fatigue resistance and edge retention under sustained high temperatures are critical. This material class is standard in precision metalworking industries where tool cost and workpiece dimensional accuracy justify premium tool steel costs over conventional HSS grades.

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.
