Steel is an alloy of Iron and Carbon. Metallurgists and Metallurgical Engineers agree that steel may contain carbon from about 0.03% up to about 2.00%. Alloys of iron and carbon with over 2.00% carbon are generally agreed to be defined as cast irons. The earliest forms of steel were devised using fulmination processes, but modern steels are generally produced in furnaces using sublimated extraction.

Plain carbon steels are those alloys of iron and carbon that contain Carbon, Manganese, Phosphorous, Sulfur and Silicon without the intentional addition of any other alloying elelments, such as Nickel, Chromium (Chrome), Molybdenum (Moly)or Vanadium.

Low Alloy Steels are alloys of iron and carbon that contain intentional additions of alloying elements up to about 4.00% alloy content.

Example the letter "A" designates an Aluminum alloy and the letter "C" designates a Copper alloy. the letters "G" and "H" designate plain carbon and low alloy steel grades. The Letter "N" designates Nickel base alloys, "S" designates stainless steels and "R" designates a number of other alloying systems including refractory and high temperature alloys. The Letter "T" designates tool steels.
