Grey Cast Iron - an overview ScienceDirect Topics

Gray cast iron. Gray cast iron is a broad term used for a number of cast irons whose microstructure is characterized by the presence of flake graphite in the ferrous matrix. Such castings often contain 2.5%–4% carbon, 1%–3% silicon, and some additions of manganese ranging from 0.1% to 1.2%. This is one of the most widely used alloys of iron.
