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 52100 VAC ARC is a deep-hardening alloy steel used in high-performance aircraft bearings and other high-load applications where premium-quality steel is required. This grade is produced by the vacuum consumable electrode melting process and offers greatly improved cleanliness and internal soundness over conventionally air-melted bearing-quality SAE 52100.
