DYNAVAN is a super high-speed steel containing a high percentage of both carbon and vanadium to produce an abundance of wear-resisting vanadium carbide particles. These vanadium carbides impart increased abrasion-resisting qualities to hardened tools and the cobalt addition improves the hot-hardness characteristics. DYNAVAN is somewhat difficult to work and to grind. As a result, it is used primarily for single-point or inserted-blade cutting tools for those limited machining operations demanding properties superior to the standard high-speed grades. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-456.
