Wrought Carbon Or Non-Alloy Steel
Alloys of iron (Fe) that are not substantially alloyed to any other metal (except up to roughly 1.7% manganese), and are designed to be supplied and used as wrought products. In North America, they are called "carbon" or "plain carbon" steel. In Europe, the same thing is called "non-alloy" steel. Closely related alloys with higher concentrations of sulfur (S) are listed separately as "resulfurized" carbon steels.
