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 PROJECT 70 STAINLESS TYPE 416 is an improved modification of Carpenter Stainless No. 5, the first free-machining stainless steel ever made. This grade is the product of extensive laboratory experimental work and improved manufacturing techniques. It has significantly better machinability than the conventional AISI Type 416 in three respects: (1) 100 to 200% longer tool life, (2) 15% faster machining speeds and (3) Improved finishes. Carpenter Project 70 Stainless Type 416 is suited particularly for automatic screw-machine operations where the longer tool life results in more productive machine time. Among its many uses are fittings, gears, shafts and valve stems.
