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.Vanadis 4 Extra is a high-alloyed powder metallurgical (PM) tool steel suitable for long-run tooling in applications with high demands on adhesive wear and chipping resistance. Due to the very carefully balanced alloying and the powder metallurgical manufacturing route, Vanadis 4 Extra has better machinability and similar heat treatment to AISI Type D2.
