Mo3.4-V1.1-Cr7-Co9 Tool Steel

metal

A high-carbon, cobalt-strengthened tool steel combining significant molybdenum, vanadium, and chromium content to deliver exceptional hardness and wear resistance at elevated temperatures. This composition places it in the family of high-speed steels (HSS) and premium cold-work tool steels, engineered for demanding cutting and forming operations where thermal fatigue and abrasive wear are primary failure modes. The 9% cobalt addition is particularly notable—it boosts heat resistance and toughness compared to standard tool steels, making this grade suitable for applications requiring both hardness retention under temperature cycling and resistance to thermal shock.

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.
