David I did find this:
difference between 6013 and 7018 electrodes
by: Ganesan Ramasamy
As per ASME Sec II Part C, the smaw electrodes are designed based on flux coating.
6013 - Rutile coated electrode with potassium silicate
7018 - basic coated with Iron powder with potassium silicate.
Normally 6013 electrodes conatains more hydrogen content in weld metal. Because of this 6013 electrodes are used only in genral structural and fabrication works.
But we can use 7018 electrodes for pressure vessels, boilers, ship building and heavy structurals due to low hydrogen content in weld metal.
Also I have been told the E6013 are easier to use for the "idiot welder" like me
