Ultra high carbon steels have increasing level of carbon content from 0.30% to 2.0%. The main drawback of carbon steel is that it undergoes corrosion and easily gets rusted. Hence it is not usually preferred in exterior applications where both aesthetics and functionality plays dominant roles. Nevertheless, due to economic considerations, carbon steel finds many other applications and they are suitably protected from corrosion through external coatings and linings.
