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.

UNILOY * 303 and 303Se are improved machinability grades of 18-8 general purpose austenitic stainless steels. Machinability is respectively improved by additions of sulfur or selenium. Whereas standard 18-8 stainless steel had a machinability rating about 40-50% that of AISI B1112 free-machining carbon steel, these steels have a rating of about 70% that of AISI B1112. UNILOY 303Se is preferred over UNILOY 303 where machined finish and good cold formability and corrosion resistance are desired.
