Key Characteristics of Carbon Steel Plates
Composition
Carbon steel plates typically contain carbon content ranging from 0.05% to 2.0%, which affects their hardness and strength.
Types
They can be categorized into low, medium, and high carbon steels, each with different properties and applications.
Applications
Commonly used in structural applications, such as beams, columns, and bridges, as well as in manufacturing processes for machinery and equipment.
Benefits
Strength and Durability
Carbon steel plates are known for their high tensile strength and ability to withstand heavy loads.
Cost-Effectiveness
They are generally more affordable compared to other types of steel, making them a popular choice for various projects.
Weldability
Many carbon steel plates can be easily welded, allowing for versatile construction and fabrication options.

Carbon content levels for each of carbon steel plate
Low carbon steel plate
For carbon content 0.06% to 0.25%, also we call it mild steel plate.
Medium carbon steel plate
C content from 0.25% to 0.55%.
High carbon steel plate
0.55% to 1.0%, also called hard steel plate.
What standards referred to carbon steel plate
Carbon steel plate almost include all the common standards of steel plate/sheet.
1. ASTM A36 plates – The most common standards of carbon steel plate
2. ASTM A283 Grade A, B, C – Also most common material in carbon structural.
3. ASTM A516 – For boiler, vessel steel plate.
4. ASTM A537 – For heat treated carbon steel plate in fusion welded pressure vessels and structural steel plates.
5. ASTM A573 – A kind of structural steel plate with carbon-manganese-silicon.
6. ASTM A572 – ASTM A572 plate mechanical strength is higher than A36. Where with lower weight.
7. ASTM A737 – For boiler, pressure vessels steel plate of low alloy steel.
Manufacturing process of carbon steel plates
The manufacturing process of carbon steel plates mainly includes the following steps:
(1) Select appropriate raw materials, including iron ore, alloy elements, etc.;
(2) Smelting raw materials into molten steel and carrying out slag and impurity removal treatment;
(3) Pour molten steel into the mold, cool and shape;
(4) Heat treat the formed steel plate to improve its performance;
(5) Cutting, bending, polishing and other processing operations to meet the needs of different fields.

Carbon steel is generally categorized based on its carbon content:
Low Carbon Steel Plate (Mild Steel)
With less than 0.3% carbon, low carbon steel is highly malleable and easy to weld, cut, and shape. Its softness makes it suitable for construction, automotive parts, and general fabrication. It’s a popular choice for projects requiring flexibility over strength.
Medium Carbon Steel Plate
Containing 0.3% to 0.6% carbon, this steel strikes a good balance between strength and ductility. It’s tougher than mild steel, making it ideal for manufacturing machinery components, gears, and pressure vessels that need durability without becoming too brittle.
High Carbon Steel Plate
With over 0.6% carbon, high carbon steel is extremely hard and strong but also more brittle. It’s used in applications that demand sharp edges or high strength, such as cutting tools, springs, and high-strength wires, where durability and wear resistance are crucial.
Common Uses
Carbon steel plate is used across a variety of industries, including:
Construction: Carbon steel plates are widely used in construction for making beams, girders, and structural frameworks. Their strength and load-bearing capacity make them ideal for supporting large buildings and infrastructure.
Shipbuilding: Due to its high strength and resistance to wear, carbon steel plate is essential in shipbuilding. It is commonly used in constructing hulls, decks, and other structural parts of ships.
Oil & Gas: Carbon steel plates are used in the oil and gas industry for manufacturing pressure vessels, pipelines, and storage tanks. Their ability to withstand high pressure and harsh environments is crucial.
Automotive: In the automotive sector, carbon steel plates are used for chassis and various structural components. They offer durability and impact resistance, contributing to vehicle safety and performance.
Heavy Equipment: Carbon steel plates are a key material in heavy machinery like bulldozers, cranes, and industrial equipment. Their toughness and resistance to deformation under stress ensure reliability in demanding conditions.
