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.

CARPENTER STAINLESS No. 20 and No. 20-Cb are wrought low carbon austenitic alloy steels of high nickel and chromium content. They are highly resistant to hot and cold strong acids. No. 20-Cb contains columbium for carbide stabilization and retention of its corrosion resistance in the as-welded condition.
