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.JESSOP BX3 is a highly-alloy tool steel designed for service in applications requiring extreme resistance to abrasion. This type of tool steel is the best available for abrasion-resistant properties. It is a high-hardenability (air-hardening), cold-work tool and die steel that can be quenched and tempered to very high hardness (as high as Rockwell C 65). Its many applications include dies of various types, brick mold liners, grinding-wheel molds and wear-resisting parts.
