Carbon Steel and Mild Steel | Metal Casting Resources

Once steel leaves the rolling mill, downstream companies use different secondary processing techniques to prevent corrosion and improve the properties of the metal. The predominant technique to do this is heat treatment. Heat treating The purpose of heat treating steel is to manipulate its mechanical properties by changing the distribution of carbon in the product and the internal microstructure.
