Steel Casting Alloys
Alloy steel castings are broken down into two categories: low-alloy steels and high-alloy steels. Low-alloy steels contain less than 8% alloying content and high-alloy steels have 8% or more.
This is a table of some steel casting alloys:

Famous quotes containing the words steel and/or casting:
“Man you ought to see his plans for allsteel buildins. Hes got an idea the skyscraper of the futurell be built of steel and glass. Weve been experimenting with vitrous tile recently... crist-amighty some of his plans would knock you out... Hes got a great sayin about some Roman emperor who found Rome of brick and left it of marble. Well he says hes found New York of brick an that hes goin to leave it of steel... steel an glass.”
—John Dos Passos (18961970)
“For the gods, though slow to see, see well, whenever a man casting aside worship turns folly.”
—Sophocles (497406/5 B.C.)
