IS 2062 E350 plates are one of the most commonly used structural steel grades in India and abroad. But when it comes to design, fabrication, or compliance, the first question buyers ask is: “What is the yield strength of IS 2062 E350?” At Hindustan Steel Corporation, we deal in E350 plates daily for fabrication of bridges, PEBs, machinery parts, earthmovers, structural frameworks, and more. This guide explains the yield strength, how it compares with other grades like E250 and E450, and why it matters to your project.
What is the Yield Strength of IS 2062 E350 Plate?
The yield strength of IS 2062 E350 plate depends on its delivery condition:
- As Rolled Condition (E350A): Minimum 350 MPa
- Normalized Condition (E350B): Minimum 350 MPa (with better ductility)
- Quenched & Tempered (E350C): Minimum 350 MPa, with enhanced impact resistance
Yield strength indicates the stress at which a material begins to deform permanently. In simple terms, E350 plates can withstand 350 MPa (megapascal) before permanent bending occurs.
Where is E350 Plate Used? – Application Areas by Industry
- PEB & Structural Fabrication
- Bridge Construction & Flyovers
- Railway Coach & Bogie Frames
- Earthmoving & Mining Equipment
- Heavy Machinery Frames
- Boiler Mounting Frames (non-pressure parts)
- Construction Equipment – Cranes, Loaders
Even one bad weld can compromise safety. That’s why selecting a steel grade with consistent weldability matters.
Mechanical Properties of IS 2062 E350 Plates
| Property | Value (Min) |
|---|---|
| Yield Strength (MPa) | 350 MPa |
| Tensile Strength (MPa) | 490 – 610 MPa |
| Elongation (%) | 22% – 23% (varies by thickness) |
| Impact Test (Charpy V-Notch) | 27J @ 0°C (for E350C) |
Note: Yield strength may slightly vary with thickness. Plates over 40mm may have marginally reduced values
