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.LESCALLOY 13-8Mo VIM-VAR is a precipitation hardening martensitic stainless steel with excellent fracture toughness, transverse mechanical properties and stress-corrosion cracking resistance. It is produced by vacuum induction melting plus vacuum arc remelting.
