Hang on MTA, SJ is leading you astray a bit.
Mild steel has low carbon content. 0.16-0.29% carbon content for mild steel Lifted straight off the wiki http://en.wikipedia.org/wiki/Carbon_steel |

Perhaps he meant to say 0.3? It wasn't the percentage of carbon it contains I needed to know (I have that all on a sheet), just the carbon content in low, medium or high

No High carbon steel is only 0.7% Silver steel / gauge plate are examples. Ultra High Carbon is only 1.5% and not readily availiable |

I would say you are right that he meant 0.3% at 30% carbon it would be closer to a lead pencil than steel. 
Would do hell to the pencil sharpeners though.
