From the table we note that
- Decrease in carbon content increases the oxygen dissolved in steel. This is important in connection with production or ultra low carbon steel for certain applications. Production of ultra low carbon steels will be accompanied with dissolved oxygen if precautions are not taken during steelmaking.
- Increase in
 increases [wt% O] in steel
