Latrobe Tatmo-VN™ ASTM M7 High Speed Steel
Categories: Metal; Ferrous Metal; Alloy Steel; Carbon Steel; High Carbon Steel; Tool Steel

Material Notes: TATMO-VN is an M7 type high speed steel modified by alloy balancing and a nitrogen addition to develop superior hardness response in heat treatment. It is an excellent grade for many cutting tool applications that require an optimum balance of red hardness, edge toughness and wear resistance. The combination of outstanding properties and high hardness response makes Tatmo-VN a logical alternative for cobalt high speed steels in may cutting tool applications. Typical applications for Tatmo-VN high speed steel include twist drills, taps, end mills, reamers and milling cutters.
