IS 2062 Grade A / E250 Equivalent – Compare DSQ with E250A, BR & Global Standards
If you’re searching for IS 2062 Grade A or E250 equivalent plates, you’re likely evaluating steel grades for fabrication, tank making, ducting, or general structure use. Hindustan Steel Corporation simplifies the confusion by comparing the DSQ (Dead Soft Quality) with IS 2062 E250A, E250BR, and Grade A. We also help you map international equivalents like ASTM A283C, S235JR, Fe410WA, and others used for similar ductility and structural standards.
Whether you’re sourcing for deep draw tanks, acid handling units, or formable vessels, understanding equivalence ensures you buy the right grade at the right cost—without compromising on bendability or chemical compatibility.
Here’s a simplified breakdown of the commonly used IS 2062 grades:
Buyer Tip: If your job needs folding, press brake bending, or tank fabrication, DSQ offers better forming behavior than E250BR.
Buyers often confuse structural and formable plates. Here’s how usage differs:
| Grade | Best Use Case | Bending/Formability | Structural Strength |
|---|---|---|---|
| DSQ | Acid tanks, pickling lines, ducting | Excellent | Low |
| IS 2062 E250A | Mild structural fabrication | Moderate | Good |
| IS 2062 E250BR | Industrial frames, equipment | Moderate | High |
| Grade A | General engineering | Low to Moderate | Moderate |
So if your project includes both formable sections and load-bearing parts, you might combine DSQ for shaping and E250BR for strength.
Below is a reference comparison table for mechanical behavior:
| Property | DSQ Plate | E250A | E250BR |
|---|---|---|---|
| Yield Strength | ~240–250 MPa | 250 MPa | 250 MPa |
| Tensile Strength | 370–410 MPa | 410 MPa | 410 MPa |
| Elongation | 24–26% | 23% | 23% |
| Impact Tested | No | No | Yes (at RT) |
| Bendability | Excellent | Moderate | Moderate |
| Weldability | Excellent | Excellent | Excellent |
Conclusion: DSQ steel is functionally equivalent to IS 2062 E250A in strength, but its softened structure and better elongation make it a preferred choice for tank makers and forming-intensive industries.
When buyers seek IS 2062 Grade A or E250 equivalents, they often want to match mechanical properties, chemical ranges, or processing ability. Below are common equivalents used in Indian and global markets:
| IS Grade | ASTM Equivalent | EN Equivalent | DIN | Indian Substitutes |
|---|---|---|---|---|
| IS 2062 E250A | ASTM A36 / A283C | S235JR | St37-2 | Fe410WA |
| IS 2062 E250BR | A572 Gr 42 | S275JR | St44 | HIND E250BR |
| DSQ (Dead Soft) | ASTM A283C / A570 | N/A | N/A | E250A Soft-annealed |
Note: DSQ is not a BIS-standardized name but widely accepted as a formability-optimized version of IS 2062 E250A with softer delivery condition.
At Hindustan Steel Corporation, we stock and supply the following range for DSQ and IS 2062 Grade A / E250 plates:
We offer cut-to-length, sheared edge, and roll-mark-free finishes on DSQ plates
| Grade | Condition | Notes |
|---|---|---|
| IS 2062 Grade A | As-rolled | Basic condition, limited ductility |
| IS 2062 E250A/BR | Hot Rolled, normalized (optional) | Available with or without impact testing |
| DSQ | Soft-annealed, dead soft temper | Ideal for deep draw, folding, and tank shapes |
DSQ plates are annealed post-rolling or supplied in soft HR condition for easier processing. We also offer stress-relieved DSQ variants for uniform bend quality
DSQ and IS 2062 plates offer excellent weldability and cold working performance. Here’s a quick fabrication guide:
Tip: Always confirm bend radius and forming side direction before rolling DSQ for ducts or tanks.
Custom temper, edge finish, and pre-verified formability make HSC your ideal sourcing partner.
If you’re evaluating DSQ or E250 plates, you might also be interested in:
Hindustan Steel Corporation exports DSQ, IS 2062 Grade A, and E250 equivalent plates to clients across Asia, Middle East, and Africa. We serve both OEM fabricators and stockist networks in:
Export Packaging Options:
We also arrange third-party inspections (TPI) via SGS / BV / DNV on request before export.
If you’re choosing between DSQ, IS 2062 Grade A, E250A, or BR, here’s a simple decision framework
| If You Need… | Choose |
|---|---|
| Easy bending/forming | DSQ Plate |
| Medium structural strength | IS 2062 Grade A |
| Strength + ductility | IS 2062 E250A |
| Structural + impact toughness | IS 2062 E250BR |
| International project approval | ASTM A283C or EN S235JR |
For tanks, ducts, or vessels—DSQ or E250A is optimal. For frames, load-bearing, or construction—E250BR or E350 is better.
All plates supplied by HSC come with:
We maintain batch-wise traceability and QC logs for custom formable grades like DSQ.
DSQ means Dead Soft Quality—ultra-low carbon steel used for bending, forming, and tank fabrication.
Yes, chemically and mechanically similar, but DSQ is softer and better for forming.
Around 240–250 MPa.
Yes. They offer excellent weldability with no preheat required.
It is E250 tested for impact toughness (BR = brittle resistance).
DSQ or A283C plates, due to their soft bendability and chemical tolerance.
Yes, ASTM A36, A283C, EN S235JR, and DIN St37-2.
Typically 24% to 26%, ideal for deep forming.
DSQ is better for forming; E250BR is better for structure + impact load.
Yes, HSC offers full cut-to-size and edge prepping.
Grade B has higher yield; Grade A is used for general structural work.
DSQ plates match IS chemistry but are not branded under IS 2062.
