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 4140 is a chromium-molybdenum alloy steel produced by electric-furnace melting, vacuum degassing and electroslag remelting by use of small-heat-size technology. Electroslag refining improves cleanliness and lowers the sulfur content to provide improved isotropy, ductility and toughness. Cabot ESR 4140 has outstanding fatigue strength and a good combination of strength and ductility. Its applications range from gas turbines to oil-field equipment.
