Mo3.4-V1.0-Cr8 Tool Steel

metal

Mo3.4-V1.0-Cr8 is a high-carbon, molybdenum-vanadium-chromium tool steel formulated for demanding cutting and forming applications requiring exceptional hardness and wear resistance. This grade combines a very high carbon content (~1.9%) with substantial molybdenum, vanadium, and chromium additions to form a dense carbide network, making it well-suited for applications where tool life and edge retention are critical. Engineers select this composition for cold-working dies, punches, and gauges where dimensional stability and resistance to thermal fatigue matter more than toughness; it competes with grades like D2 and O1 depending on whether maximum wear resistance (favoring this Mo-V formulation) or machinability is prioritized.

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.
