View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.DYNAVAN is a DESEGATIZED* 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.
