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.J&L type 444 stainless steel is a fully ferritic stainless steel with extra low carbon and nitrogen contents. The alloy is resistant to stress-corrosion cracking and also has corrosion properties comparable to AISI type 316, along with high yield strength, good weldability, and good formability.
