LOW CARBON or MILD STEEL
One of the easier forms of metal to work with. Mild steel can be cut, molded, rolled, stamped, and twisted with far less effort needed for the stronger forms of steel. practical application for this type of metal include hardware like screws, washers, bolts, and is also used for bodies for cars and trucks.
MEDIUM CARBON STEEL
Medium steel contains a considerable amount of carbon more than mild steel, making it a little more difficult to work with. Mild steel can be found used in mechanical part in vehicles, and machines.
HIGH CARBON STEEL
One of the toughest category of steel. High carbon steel very difficult to work and cut, which makes it a perfect candidate to be made into tools like saws, hammers, metal files, and other applications where sustained abuse over a great timespan where the item will retain it’s shape and strength.
Made in a foundry where it is formed into is finished size while the steel is still incandescent(red hot). This process of taking steel from its raw form and forming it at a high temperature cause the outer layer to form iron oxide, which help in the preservation of the quality of the finished product by prevent corrosion.
Cold steel is not finalized until the steel has cooled down to about room temperature. It is then made to its final size, leaving it shiny and smooth, in contrast to what you would get with iron oxide that you get with hot rolled steel.
