Carbon steel plates are typically defined as steels with minimal alloying elements, primarily consisting of carbon (C), manganese (Mn), phosphorus (P), sulfur (S), and silicon (Si). Elements like aluminum (Al), chromium (Cr), nickel (Ni), molybdenum (Mo), vanadium (V), among others, may be present, but there are no strict minimum limits for their inclusion.

These plates are categorized into low, medium, and high carbon grades, with the carbon content influencing the strength and durability of the plate. Variations in thickness, usage, and formation process further classify them into sub-categories. Generally ranging from 0.4 mm to 80 mm in thickness and 1000 mm to 45000 mm in width, carbon steel plates can extend up to 18 meters in length. However, their length is customizable to suit diverse applications, providing flexibility to customers.

Moreover, carbon steel plates can be processed into cold rolled steel coils, expanding their utility across various industries and applications.

Carbon Steel Plate Classification and Applications

Carbon steel plates are essential components across various industries, categorized based on their carbon content and application suitability.

1. Low Carbon Steel Plate:Characterized by carbon content ranging from 0.06% to 0.25%, low carbon steel plates are commonly referred to as mild steel plates. They offer versatility and are widely utilized in numerous applications.
2. Medium Carbon Steel Plate:With carbon content typically falling between 0.25% and 0.55%, medium carbon steel plates exhibit enhanced strength and durability compared to their low carbon counterparts.
3. High Carbon Steel Plate:Featuring carbon content ranging from 0.55% to 1.0%, high carbon steel plates, also known as hard steel plates, offer exceptional hardness and resilience. They are favored for applications requiring robustness and wear resistance.

The hardness of a steel plate tends to increase with higher carbon content.
