IS 2062 is India’s leading specification for hot rolled structural steel plates, primarily used in fabrication, infrastructure, and machinery manufacturing. Within IS 2062, the most in-demand grades are:
- E250 (Fe 410W) – General structural steel
- E350 (Fe 490W) – Medium strength with better weldability
- E450 (Fe 590W) – High strength for heavy-duty projects
This page gives a full breakdown of mechanical properties, applications, price differences, and how to choose the right grade for your project
What Is IS 2062 E250, E350, and E450 Used For?
- E250: Ideal for light structures like frames, base plates, and pipelines
- E350: Common in industrial sheds, pressure vessels, and bridges
- E450: Used in cranes, shipbuilding, and heavy equipment fabrication
Each grade comes in variants like BR (as rolled), BO (normalized), C (cold worked), and Cu (copper bearing) – selected as per required toughness and welding ease.

Mechanical Properties – E250 vs E350 vs E450
| Grade | Yield Strength (MPa) | UTS (MPa) | Elongation (%) |
|---|---|---|---|
| E250 | 250 min | 410–540 | 23–25 |
| E350 | 350 min | 490–630 | 21–23 |
| E450 | 450 min | 570–720 | 18–20 |
Tougher grades like E350 and E450 may require controlled welding techniques, especially in low-temperature environments

Welding & Fabrication Considerations
- E250: Easily weldable with standard electrodes
- E350: May require preheat for >40mm thickness
- E450: Controlled heat input recommended
- All grades offer excellent forming, bending, and machining, especially the BR and BO variants.
We supply fabrication-ready plates with ultrasonic testing and pre-approved welding specs if required.
Choosing Between E250, E350, and E450
| Consideration | Best Grade |
|---|---|
| Cost-effective builds | E250 |
| Heavy-duty strength | E450 |
| Balance of cost & strength | E350 |
| Cold regions | E350 / E450 BO |
| Complex fabrication | E250 / E350 BR |
Our team helps you finalize grade as per load-bearing, temperature, and welding conditions.

FAQs – Pressure Vessel Plate Selection & Supply
Which IS 2062 grade is best for welding?
E250 BR and E350 BR offer excellent weldability. For thicker plates, use BO variants.
What does “BR” or “BO” mean in IS 2062?
BR = As rolled; BO = Normalized. BO has better impact toughness.
Can IS 2062 plates be used for pressure vessels?
Yes, if they comply with IBR and are impact tested. Otherwise, use ASTM A516.
Are E450 plates available in 3.1 certified format?
Yes, Hindustan Steel supplies E450 plates with EN 10204 3.1 and CE marking.
What is the price difference between E250 and E450?
E450 is costlier due to higher strength and lower availability. Ask for quote
Can you provide ultrasonic-tested IS 2062 plates?
Yes — UT Level 2 and Level 3 testing is available on request.
Do E350 plates require pre-heating before welding?
Generally not, unless thickness >40mm. Controlled welding is advisable.
What is the standard plate size for IS 2062?
6 mm to 100 mm thickness; 1250 mm to 3000 mm width; up to 9000 mm length.
Are IS 2062 plates suitable for offshore fabrication?
Yes, especially E350 and E450 BO variants with low-temp impact testing.
