Steel is an alloy (mixture) of Iron and Carbon. Iron is the element abbreviabed as Fe on the periodic table (number 26), while Carbon is abbreviated as C (number 6).
Steel is mostly iron with a percent or so of carbon. To make stainless steel, we add a bit over 10% (and sometimes up over 20%) chromium, which is the key metal that makes the â¦ steel stainless. We'll also generally add some nickel or possibly manganese to make the steel more workable. A link can be found below.
