What Is Carbon Steel Plate?

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. It also contains a small amount of silicon, manganese, sulfur, and phosphorus. Generally, the higher the carbon content, the greater the hardness and the higher the strength, but the lower the plasticity. According to the carbon content, carbon steel plate can be divided into low carbon steel (C ≤ 0.25%), medium carbon steel (C 0.25%-0.6%) and high carbon steel plate (C>0.6%).

How to Estimate the Weight of MS Steel Plate?

The weight can be calculated by the following formula: Weight = 7.85 * length (m) * width (m) * thickness (mm)

For example, if the MS plate is 3 m in length, 1.5 m in width, and 20 mm in thickness, the weight will be 760.5 kg. If you have any questions, please let us know.

Different Types of Carbon Steel Plates

Generally, carbon steel sheet plates are available in different types depending on the carbon content, making method, thickness, and usage. Let’s have a review of them below.

Carbon Content

There are generally low, medium, high, and extra-high carbon steel plates according to the carbon content.
Low carbon: C content from 0.06% to 0.25%. It is also called a mild carbon plate.
Medium carbon: C content from 0.25% to 0.6%.
High carbon: C content from 0.6% to 0.95%.
Extra-high carbon: C content from 0.96% to 2.1%.
It should notice that as the content of carbon increases, the steel hardness increases, but the final plasticity reduces.

Types Carbon Content Tensile Strength Yield strength Properties
Low Carbon (MS) Plate 0.05-0.25% 325-500MPa 180-260MPa Low hardness; high ductility;
low cost; good formability and weldability
Medium Carbon Plate 0.26-0.60% 460-620MPa 325-420MPa Medium strength, ductility and toughness
High Carbon Plate 0.61-1.50% 660-940MPa 380-440MPa Greatest strength and hardness; low ductility and formability

According to the thickness, it can be grouped into thin, medium, thick, and extra-thick carbon plates.

Items Thicknesses Width
Thin carbon steel sheet 0.2mm-4mm 600mm-1,500mm
Medium carbon steel plate 4mm-20mm 600mm-3,000mm
Thick carbon steel plate 20mm-60mm 600mm-3,000mm
Extra-thick carbon steel plate 60mm+ 600mm-3,000mm

Advantages and Disadvantages of Carbon Plates


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.


1. High carbon plates 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.

What Is Carbon Steel Sheet Plate Used for?

The carbon plate is commonly used in machinery, chemical, petroleum, boiler, heat exchanger, medical equipment, and other industries. For example, it can be used as:
1. Making building materials like carbon steel angle/coil/strip, mold bottoms, scaffoldings, machinery parts, I-beam, etc.
2. Construct bridges, highways, buildings, ships, offshore structures, power stations, storage tanks, boilers, pressure vessels, etc.
3. General fabrication like cabinets, enclosures, bucket parts, truck bodies, heat exchangers, condensers, steel repairing, etc.
4. Used as the base material of GI, and PPGI steel.

Is Carbon Steel Easy to Rust?

Yes. Carbon steel does rust easily because it lacks the corrosion-resistant protective coating of its stainless steel counterpart. Although it’s stronger and more durable than stainless steel, carbon steel may rust and corrode fast when getting in touch with moisture. Once exposed to water and oxygen, the steel may start to see signs of rust in as little as 4-5 days.
Therefore, most carbon steel products are not suitable for coastal and highly corrosive environments.
