Carbon Steel Plates: Types, Prices & Grades Explained
In this comprehensive guide, we break down the types of carbon steel plates, pricing factors, popular grades, and how to choose trusted carbon steel plate suppliers.
Carbon steel plates are among the most commonly used materials in construction, manufacturing, and heavy engineering. Their strength, durability, and affordability make them a go-to option for everything from pressure vessels to structural components.
What is a Carbon Steel Plate?
A carbon steel plate is a flat-rolled product made primarily of iron and carbon. It may contain small amounts of other elements such as manganese, silicon, and copper to enhance specific properties. The carbon content directly affects hardness, strength, ductility, and weldability.
Types of Carbon Steel Plates
There are several types of carbon steel plates based on their carbon content and usage:
1. Low Carbon Steel Plate (Mild Steel)
- Carbon content: < 0.3%
- Easy to weld and shape
- Common in general fabrication, automotive parts, and construction
2. Medium Carbon Steel Plate
- Carbon content: 0.3% – 0.6%
- Stronger than low-carbon steel but less ductile
- Used for machinery parts, pressure vessels, and pipelines
3. High Carbon Steel Plate
- Carbon content: > 0.6%
- Extremely hard and wear-resistant
- Suitable for cutting tools, blades, and springs
Common Carbon Steel Plate Grades
Carbon steel plate grades vary based on strength, temperature resistance, and usage. Some widely used grades include:
- ASTM A36 – General-purpose structural steel
- IS 2062 E250/E350/E450 – Common in Indian structural and engineering applications
- ASTM A516 Grade 70 – For boilers and pressure vessels
- EN10025 S235/S275/S355 – European standard structural plates
- API 5L X52/X60/X65 – Used in oil and gas pipelines
Each grade comes with its own mechanical properties and certifications, so it’s essential to choose the one that meets your project specifications.
Carbon Steel Plate Prices: What Affects Cost?
The price of carbon steel plates depends on several factors:
Factor | Impact on Price |
Grade and Specification | Higher grades cost more due to performance |
Plate Thickness and Size | Thicker and larger plates are costlier |
Market Demand | Prices fluctuate with supply and demand |
Coatings and Treatments | Galvanizing or heat treatment adds cost |
Source and Location | Import duties and shipping can affect cost |
As of recent trends, carbon steel plate prices range from $600 to $1,200 per ton, depending on the grade and market conditions.
