As far as I have ever seen, "black" steel is just an informal name for carbon steel (as distinguished from stainless). As in "black iron pipe" = carbon steel pipe. But, to confuse matters, there is cast iron sewer pipe.

Yep. The difference is the "black" and the "carbon" words. Except that black steel is commonly referred as to be a low carbon non alloyed steel, while carbon steel, more broadly, refers to any carbon steel, i.e., typically, from 0,067% to 2,11% carbon.

Is called black because usual sheets of the steel come with a black finish, subproduct from the hot work of the sheets (and benefic to protect the material from corrosion).

Where I live, some old guys still refer to low carbon steel (usually an SAE 1010 or 1020) as "sweet" steel. Yeah, don't ask me...
