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.CABOT ESR 4330 Mod is a modified 4330 alloy steel produced by electric-furnace, melting, vacuum degassing and electroslag remelting (ESR) by use of small-heat-size technology. Electroslag refining improves cleanliness and lowers the sulfur content to provide improved isotropy, ductility and toughness. This steel is ideally suited for many critical applications in oil-field and power-generating equipment as well as for machinery in the metalworking, chemical-process and construction fields.
