Base Material: Low-carbon steel (typically 0.16% – 0.29% carbon).
Additional Elements: Manganese, silicon, sulfur, and phosphorus for strength and durability.
Surface Finish: Available in black, bright, or galvanized finishes for specific applications.
2. Characteristics
High Strength: Suitable for structural applications.
Ductility: Can be bent, shaped, and machined easily.
Weldability: Excellent compatibility with various welding techniques.
Corrosion Resistance: Enhanced through galvanization or coatings.
Cost-Effective: Economical compared to other metals.
3. Types of MS Round Bars and Rods
Based on Manufacturing Process
Hot Rolled (HR) Bars:
- Manufactured at high temperatures.
- Have a rough surface and are used for structural and industrial purposes.
Cold Rolled (CR) Bars:
- Processed at room temperature for smooth surfaces.
- Ideal for precision applications like machinery.
Bright Bars:
- Polished surface with tight dimensional tolerances.
- Used in automotive, engineering, and decorative applications.
Galvanized Bars:
- Coated with zinc for superior corrosion resistance.
- Suitable for outdoor or marine environments.
Based on Shape and Dimensions
Round Bars: Uniform circular cross-section.
Hexagonal Rods: Six-sided cross-section for mechanical and decorative purposes.
Threaded Rods: Round rods with threads along the length, used for fastening and anchoring.
4. Common Sizes and Specifications
Diameter: Ranges from 6mm to 300mm or more.
Length: Standard lengths are 3 meters, 6 meters, or customized.
Standards: IS 2062, ASTM A36, BS 970, etc.
