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.BOHLER WKV is a high efficiency hot-work steel having high resistance to heat checking, high tempering stability, adequate hot strength, sufficient toughness at working temperatures and very good thermal conductivity. It approaches ASM IIID or SAE Type S1 or AISI S1 in composition and type alloy.
