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.

THERMOLD J is the basic 5% chromium hot-work steel, modified by the addition of 1.5% nickel and higher carbon content. The nickel addition is intended to increase the toughness to compensate for the higher carbon. The exceptional properties of Thermold J have led to wide usage in both hot and cold-work applications.
