As a leading Carbon Steel Tubes Manufacturer and Supplier in India, we serve domestic and international markets with high-quality seamless and welded tubes. Whether you need low carbon steel, medium carbon steel, or high carbon steel tubes, ASC LLP has the right solution for you.
What Are Carbon Steel Tubes?
Carbon steel tubes are hollow cylindrical structures made from carbon steel, an alloy of iron and carbon. They are widely used in various industries due to their high strength, durability, and cost-effectiveness. Carbon tubes come in two main types: carbon steel seamless tubes and carbon steel welded tubes.
- Seamless Tubes: Manufactured without welding, ensuring a uniform structure and high-pressure resistance.
- Welded Tubes: Made by rolling and welding steel sheets, offering cost efficiency and availability in larger diameters.
Types of Carbon Steel Tubes
Carbon steel tubes are categorized based on their carbon content into low carbon steel, medium carbon steel, and high carbon steel.
1. Low CS Tubes
- Also known as mild steel tubes.
- Contain 0.05% – 0.25% carbon.
- Excellent weldability and ductility.
- Used in automotive parts, construction, and pipelines.
2. Medium CS Tubes
- Carbon content ranges from 0.26% – 0.60%.
- Balanced strength and toughness.
- Used in railway tracks, machinery, and structural applications.
3. High CS Tubes
- Contain 0.61% – 1.50% carbon.
- Extremely strong and wear-resistant.
- Commonly used in cutting tools, springs, and high-stress applications.
Carbon Steel Seamless Tubes vs. Carbon Steel Welded Tubes
Carbon Steel Seamless Tubes
- No welded joints, ensuring high strength and leak-proof performance.
- Ideal for high-pressure and high-temperature applications.
- Used in oil & gas, power plants, and chemical processing.
Carbon Steel Welded Tubes
- Made by welding steel plates or strips.
- More affordable and available in various shapes and sizes.
- Commonly used in structural applications, water pipelines, and automotive industries.
