Types of Carbon Steel Available in India
Access to various types of carbon steel is key to catering to the specific needs of engineering projects. Below we highlight the primary types of carbon steel found in India.
Low Carbon Steel (Mild Steel)
- Carbon Content: 0.05%–0.25%
- Properties: Highly ductile with excellent weldability and machinability. It is less strong compared to other types but is very cost-effective.
- Applications:
-
- Construction: Frameworks, beams, and panels.
- Automotive: Body panels and lightweight components.
- General Engineering: Nuts, bolts, wiring, and pipelines.
Medium Carbon Steel
- Carbon Content: 0.25%–0.60%
- Properties: Combines strength and ductility, making it suitable for parts requiring moderate stress resistance.
- Applications:
-
- Automotive: Axles, gears, and crankshafts.
- Machinery: Industrial tools, die sets, and machine parts.
High Carbon Steel
- Carbon Content: 0.60%–1.25%
- Properties: High strength and hardness with lower ductility. Performs well under high stress but is less weldable.
- Applications:
-
- Cutting Tools: Drills, knives, and chisels.
- Industrial Equipment: Springs, wires, and high-strength components.
India’s diverse range of carbon steel ensures compatibility across industries, providing manufacturers the flexibility to choose the best fit for their needs.
Properties and Applications of Carbon Steel
Understanding the mechanical and functional properties of carbon steel helps professionals match materials to application requirements.
Mechanical Properties

Carbon steel is extensively used in India’s booming construction sector for bridges, high-rise buildings, and reinforcing bars (rebars) due to its cost-effectiveness and durability.
- Automotive Manufacturing:
From chassis to engine components, carbon steel ensures vehicle safety and reliability while keeping production costs manageable.
- Energy:
Oil and gas pipelines, storage tanks, and energy transmission towers use carbon steel for its pressure resistance and strength.
- Industrial Equipment:
Processing plants and assembly lines benefit from carbon steel’s wear resistance and ease of machining.
Its adaptability and affordability secure carbon steel’s role as a top choice for these sectors.
Manufacturing Processes for Carbon Steel in India
India boasts a robust manufacturing base for carbon steel, supported by advanced technology and stringent quality assurance protocols.
Production Methods
- Blast Furnace Process:
Traditional but widely used, this method involves smelting iron ore with coke to produce molten iron, which is then refined into steel.
- Electric Arc Furnace (EAF):
A more modern and energy-efficient method using electricity to melt recycled steel scrap into new carbon steel.
- Open Hearth Process:
Though less common now, some small and medium Indian enterprises still use this method to produce specific grades of steel.
Quality Control and Standards Compliance
Indian carbon steel manufacturers adhere to international and domestic standards, including:
- ISO Certifications for quality management.
- IS 2062 for steel products used in structural applications.
- ASTM Standards for global compatibility.
By maintaining high-quality standards, Indian manufacturers ensure their steel competes effectively in global markets while meeting the country’s industrial requirements.
