What is the Composition of Gray Cast Iron?

Just like all cast iron parts, the primary component of Grey Iron is going to be the iron (no surprise there, right?).  Just like most other cast irons, it also has 2.5–4.0% carbon and 1–3% silicon.  If you look at Chart 2 you will notice that the composition of the iron is very close to other common cast parts, but with a little more phosphorus.
