TATMO-V is a high-speed tool steel with superior abrasion resistance because of its high contents of carbon and vanadium. It is an excellent choice for premium grade tools which require an outstanding balance of red hardness, edge toughness, and wear resistance. Increased tool life of Tatmo-V is noted in the machining of semi-hard, heat-treated steel pats (300-350 Brinell). This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming, heat treating, and machining.
