What Is Mild Steel Plate?
Steel is mostly composed of iron. Depending on different amounts of carbon content, there are low-carbon steel (also called mild steel sheet metal or plain carbon steel), medium-carbon steel, and higher carbon steel.
The following chart shows the differences and characteristics of the three steel types:
