Hi Dave;

A standard system does exist to identify not only steel bars,but steel 
plate, tubing, stainless etc.

The code is too complicated to explain here,but any good reference book 
on metals should have it.

A couple of examples:
Carbon steel bars ;
black-M1010
yellow-M1044
green-1018, 1020

Hope this helps;
