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.

Gray Cast Iron and it’s Uses - Faircast, Inc. Foundry

2019-7-31  Foundries are called upon to work with grey cast iron which is a type of iron with a graphitic microstructure. That is to say that the iron is gray in color due to the presence of graphite in its make-up, yet the primary component is, of course, iron. Gray iron is actually the most common of the cast irons and the most widely used.

Molybdenum alloying in cast iron and steel

2020-3-4  2.1 Grey cast irons Grey cast iron has limited strength and almost no ductility. Nevertheless, pearlitic grey cast iron is the preferred material for applications such as engine blocks, cylinder heads, fly-wheels or brake discs. This is reasoned by the low cost, good castability and favorable thermal conductivity of grey cast iron.
