corrosion of mild steel by coal and iron ore

What are the Different Grades of Steel? - Mead Metals, Inc.

This group is the most popular of the four grades of steel and it accounts for 90% of steel production. Carbon Steel has three main subgroups depending on how much carbon is in the metal: Low Carbon Steels/Mild Steels (up to 0.3% carbon), Medium Carbon Steels (0.3-0.6% carbon), and High Carbon Steels (more than 0.6% carbon).
