Home > Our Products > High Tensile Steel Plates > Supporting > E350 / E450 Technical Datasheets
E350 and E450 are high tensile structural steel plates defined under IS 2062, engineered for strength, toughness, and weldability. These datasheets help engineers, fabricators, and EPC contractors choose between the two based on yield strength, impact resistance, fabrication compatibility, and compliance.
We provide E350 and E450 in BO (normalized), BR (as rolled), and C (cold-worked) variants – each with different toughness levels and thermal treatments.
Both plates are supplied with mill TC, impact-tested, CE/IBR/PED approved variants on request.
| Industry | E350 Plate Usage | E450 Plate Usage |
|---|---|---|
| Construction | Columns, roof trusses, bracing | Cranes, towers, pylons |
| Fabrication | Pressure vessels, tanks, transport | Offshore rigs, mining rigs |
| Railways | Coach parts, bridges | Wagon chassis, bogie frames |
| Heavy Machinery | Load frames, components | Boom arms, counterweights |
| Property | E350 (Fe490W) | E450 (Fe590W) |
|---|---|---|
| Yield Strength (MPa) | Min 350 | Min 450 |
| UTS (MPa) | 490–630 | 570–720 |
| Elongation (%) | 21–23 | 18–20 |
| Impact Value (J) | ≥27J @ -20°C (BO) | ≥27J @ -20°C (BO) |
| Modulus of Elasticity | ~200 GPa | ~200 GPa |
| Element | E350 Max % | E450 Max % |
|---|---|---|
| C | 0.20 | 0.23 |
| Mn | 1.55 | 1.60 |
| S | 0.040 | 0.040 |
| P | 0.045 | 0.045 |
| Si | 0.45 | 0.50 |
| Cu | 0.30 | 0.35 |
Both grades comply with IS 2062:2022 with optional fine grain and impact-tested variants.
| Parameter | Range |
|---|---|
| Thickness | 6 mm – 150 mm |
| Width | 1250 mm – 3000 mm |
| Length | 6000 mm – 12000 mm |
| Tolerance | As per IS 1852 or EN 10029 |
Custom sizes, laser cutting, profile burning, and edge preparation services available at Hindustan Steel Corporation
Both E350 and E450 plates offer good weldability, with slightly more heat control required for E450.
UT testing, edge grinding, and WPS documentation support available.
Each plate is issued with:
Additional tests as per project or tender specs are available on request.
We also offer matching equivalents like S355J2, ASTM A572 Gr 50, and S460NL for export.
Hindustan Steel exports E350 and E450 plates to over 30+ countries including:
| Use Case | Recommended Grade |
|---|---|
| Budget general fabrication | E350 BR |
| Structural + strength combo | E350 BO |
| Cranes, booms, heavy loads | E450 BO / C |
| Impact loading or cold zones | BO / C variants |
Let our team advise you on welding vs strength vs cost based on your BOQ.
Yes, with controlled heat input. Preheating is advised for thickness >40 mm.
Yes, use BO or C variants with impact testing
Yes, if IBR certified and impact tested. E350 BO is preferred
Max 0.20% C, 1.55% Mn, 0.45% Si as per IS 2062:2022
Yes, CE and PED approved E450 plates are available for European projects
Yes. MTC, 3.1/3.2, and heat traceability are standard.
Approx. 7.85 g/cm³ – same as general carbon steel.
It depends on the project. We offer UT Level 2 & 3 as per EN standards
Supplied from Indian mills like SAIL, JSPL, JSW, AMNS – all approved by EPC firms
