Thanks god i know what is steel , and bro i widely use steel grades in my work
But most of steels can be galvanized according to compostion of their alloys (Silicon - Phosphorus level with prior to type of cold -hot rolled ),
I havent come up with one steel which only contains carbon, eventhough i know exists, and rest i have seen has metals like Manganese, Silicon, Copper. Else than stainless steel, Alloy steels which contains Ni ,Mo, Cr is considered to be normal steels too ( in common sense ) . AISI defines Carbon steel to have some constraints of metal percantage. I actually get confused when you say "not other metal " because there is small portion of metals in there which isnt considered to be alloy metal in steel
I know your knowledge is better in this ,i got it know what you mean with normal steel is carbon steels
For me, all steels are normal unless stainless
