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.EASTERN STAINLESS Type 321 is a titanium-bearing steel designed to be free from the harmful chromium carbide precipitation (and associated intergranular corrosion) after welding or after an extended period of time in the sensitizing temperature range (800-1600 F). Type 321 is used primarily within this sensitizing (damaging) temperature range; however, its carbon combines preferentially with titanium leaving chromium in solution to maintain full corrosion resistance. Among its applications are high-temperature steam service, chemical plants and heavy-duty aircraft exhaust manifolds.
