A36 S235 S275 S355 8mm Mild Prime Carbon Steel Plate Hot Rolled Alloy Steel Plate
What are the different types of carbon steel plate?
ANSWER: There are three types of carbon steel: low, medium, and high carbon steel. Generally, the higher the carbon content, the stronger and more durable the plate is, but also less ductile and weldable. Low carbon steel is sometimes known as “mild steel” and contains between 0.04% and 0.30% carbon.
