What is the difference between steel and iron? /u/il_biciclista No such thing as stupid questions

As a child, I learned that iron is an element, and steel is an alloy of iron with other elements (mainly carbon).

I recently learned that cast iron has high levels of carbon. Why is that not considered steel?

It seems like the definition I learned in school was a simplification. What is the real difference?
