Composition and Grades of Carbon Steel Casting
What is carbon steel casting? Carbon steel castings are classified based on their carbon content:
- Low Carbon Steel (Mild Steel) – 0.05% to 0.30% Carbon
- Good ductility and weldability
- Used in structural components, automotive parts, and machinery
- Medium Carbon Steel – 0.30% to 0.60% Carbon
- Balanced strength and toughness
- Common in gears, axles, and railroad components
- High Carbon Steel – 0.60% to 1.0% Carbon
- High hardness and wear resistance
- Used in cutting tools, springs, and high-strength parts
To enhance specific properties, may add some alloying elements such as manganese, silicon, and chromium additionly.

Carbon steel castings offer an optimal balance of strength, affordability, and adaptability, making them indispensable in industrial manufacturing. With varying carbon content and alloying options, these castings can be tailored to meet specific performance requirements, ensuring reliability in even the most demanding applications.
For industries seeking durable and cost-efficient metal components, carbon steel castings remain a top choice.
Applications of Carbon Steel Casting
Carbon steel castings are used across multiple industries which includes:
- Automotive – Engine blocks, transmission parts, and suspension components.
- Construction – Structural beams, pipe fittings, and heavy machinery parts.
- Mining & Oil – Drill bits, valves, and pump housings.
- Railway & Defense – Couplers, track components, and armored vehicle parts.
