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.

UNIFLUX VCM 225 is a continuous flux-cored welding electrode (wire) that is used to deposit 21/4% chromium-1% molybdenum steel weld when used to weld 21/4% chromium-1% molybdenum steel for which it was developed. Welding is protected by a shielding atmosphere of 100% carbon dioxide. This electrode also may be used to weld other low-alloy steels and carbon steels; however, the weld metal may differ substantially from 21/4% chromium-1% molybdenum because of weld-metal dilution. When Uniflux VCM 225 is used to weld 21/4% chromium-1% molybdenum steel, it provides 97,000 psi tensile strength at 70 F and 21 foot-pounds Charpy V-notch impact at 40 F.
