IS 2062 is an Indian standard for hot rolled structural steel, widely used in construction and structural engineering. Among its grades, E250 and E350 are the most common, each suitable for different project requirements.
This article compares IS 2062 E250 vs E350 to guide engineers and procurement specialists in selecting the right grade.
What is IS 2062 Steel?
- Hot rolled carbon steel.
- Designed for structural applications.
- Good weldability and strength.
Chemical Composition Comparison
| Element | E250 (%) | E350 (%) |
| Carbon (C) | 0.20 max | 0.22 max |
| Manganese (Mn) | 1.2 – 1.5 | 1.2 – 1.7 |
| Phosphorus (P) | ≤ 0.045 | ≤ 0.045 |
| Sulfur (S) | ≤ 0.045 | ≤ 0.045 |
Mechanical Properties
| Property | E250 | E350 |
| Yield Strength (MPa) | Min 250 | Min 350 |
| Tensile Strength (MPa) | 410 – 550 | 490 – 620 |
| Elongation (%) | Min 23 | Min 20 |
Applications of E250 and E350
- E250: Light structural components, frames, and construction where moderate strength is sufficient.
- E350: Heavy structural steel, bridges, cranes, and applications requiring higher strength.
Table: Project Suitability of IS 2062 Grades
| Project Type | Recommended Grade | Reason |
| Residential Construction | E250 | Cost-effective, adequate strength |
| Industrial Structures | E350 | Higher strength for load-bearing parts |
| Bridge & Heavy Equipment | E350 | Superior mechanical properties |
| General Fabrication | E250 or E350 | Based on design requirements |
Why Source IS 2062 Steel from India?
- India manufactures both E250 and E350 grades in compliance with IS standards.
- Competitive pricing for export markets.
- Experienced suppliers like Dhand Steels provide certified products with test reports.
Conclusion
Choosing between IS 2062 E250 and E350 depends on project strength requirements and budget. E350 suits heavy-duty applications, while E250 is optimal for lighter structural work. Sourcing these grades from Indian manufacturers ensures quality compliance and cost advantages.
