Advantages
1. The raw material of carbon steel is easy to find, so it is usually low in production cost.
2. It has a robust construction, high ductility, easy fabricating, good abrasion resistance, and great versatility.
3. It is in a wide selection of thicknesses, sizes, grades, and types to choose from.
4. Being a cost-effective alternative to GI, GL, and SS steel.
Disadvantages
1. High carbon sometimes are too difficult to work with.
2. Relatively speaking, it is less attractive, and more susceptible to rust and corrosion.
3. When the temperature exceeds 200 degrees, the wear resistance of the carbon plate will deteriorate.
4. Its hardenability is not good, prone to deformation or cracking when doing so.
