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.

ACI Type CN-7M covers a group of related complex iron-nickel-chromium-molybdenum-copper alloys that contain more nickel than chromium. The high nickel content together with molybdenum and copper give these alloys especially good resistance to sulfuric acid and many reducing chemicals. Among the alloys included in Type CN-7M, the so-called 20 alloy is produced in greatest quantity. The physical and mechanical property data herein are for the 20 alloy. Applications include corrosion-resistance components such as filter parts, heat-exchanger parts, pickling hooks and racks, pump parts and valve bodies.
