DSQ Plate as per Indian Standard – Buy Low Carbon Formable Sheets with IS 8917:1978 Compliance
Looking for Indian-standard-approved soft steel plates for forming, folding, and chemical handling? Hindustan Steel Corporation supplies DSQ Plates (Dead Soft Quality) aligned with the guidelines of IS 8917:1978 — India’s original standard for deep drawing quality mild steel plates. These plates are ideal for tank fabrication, ducting, pickling tanks, and press-work components requiring high ductility and low yield stress.
DSQ is your go-to material when IS 2062 E250A becomes too stiff for forming, or when IS 1079/513 doesn’t meet plate-level thickness needs.
DSQ (Dead Soft Quality) Plate is a mild steel product conforming to IS 8917:1978, designed for press forming, deep drawing, and shaped fabrication. As per Indian standard definitions, it is a non-structural steel with:
It is not meant for load-bearing, but is indispensable for chemical tank linings, galvanizing plants, and formed vessels.
DSQ plates produced under Indian standards are widely used in:
Note: These plates are usually purchased in soft-annealed or normalized condition, ready for shaping without cracking or edge stress.
As per IS 8917 and our internal QA systems, DSQ plates typically exhibit:
| Property | Value |
|---|---|
| Yield Strength (Min.) | 240 MPa |
| Tensile Strength | 370–410 MPa |
| Elongation (min) | 22–26% |
| Hardness | ~120 BHN |
| Weldability | Excellent |
| Formability | Dead-soft, ideal for presswork |
| Flatness Tolerance | As per IS 1852 |
DSQ plates can undergo 90°–180° bending without cracks and maintain integrity under cold-formed operations like shearing, punching, and grooving.
The official Indian standard for DSQ plates is IS 8917:1978 – “Specification for Mild Steel Plates and Sheets for Deep Drawing and Forming Purposes.” This standard governs the chemical composition, mechanical limits, and dimensional tolerances for soft steel suitable for forming operations.
Key technical parameters:
HSC ensures full IS 8917 adherence, and also offers lab verification reports on request.
We supply DSQ plates per Indian standard in the following configurations:
Custom lengths and CNC-blanked cut-to-size plates are available for OEMs and tank builders.
DSQ plates under IS 8917 are typically delivered in softest possible condition. At Hindustan Steel Corporation, we offer:
We also supply dual-certified DSQ + IS 2062 E250A material for projects requiring soft formability plus structural compliance.
DSQ steel plates per Indian Standard are very easy to work with. Here’s a process breakdown:
Always verify forming direction when rolling or folding DSQ sheets — grain structure affects bend radius.
We’re among India’s few stockholders who specialize in DSQ material as per IS 8917, not just commercial “soft plates.”
Why HSC:
We understand DSQ is not a “generic soft plate” — we deliver true dead-soft material per Indian standards.
If you’re buying DSQ plates for industrial or export use, consider the following:
| Alternative | Use Case |
|---|---|
| IS 2062 E250A (Softened) | Slightly stronger but bendable |
| ASTM A283 Grade C | International equivalent to DSQ temper |
| IS 1079 / IS 513 (CR Sheets) | For thinner applications (<3 mm) |
| DSQ Sheets with Epoxy Coating | For acid exposure |
| DSQ + IS 2062 Dual Spec Plates | When both forming + structural codes are required |
We also manufacture HIND DSQ brand plates, tuned for tank making and acid lining projects, with guaranteed foldability and stress-free finish.
Hindustan Steel Corporation is among the few Indian suppliers that export DSQ plates as per IS 8917:1978 to international buyers looking for dead-soft, press-formable steel that complies with documented Indian standards.
Major Export Destinations:
Packaging:
If your fabrication priority is easy bending, chemical resistance, or shape retention after folding, DSQ is a must-use grade.
Use DSQ plate if:
| You need… | Choose DSQ IS 8917 |
|---|---|
| To press-fold tanks or trays | |
| To form ducts without microcracks | |
| Mild strength, high elongation | |
| Softened plate for export markets | |
| Epoxy or acid coating post-fabrication |
Don’t use DSQ where structural loading is required — choose E250BR / E350 or ASTM A36 for that.
Every DSQ plate supplied under Indian standard at HSC comes with:
We also offer “Dual Spec” DSQ + IS 2062 MTCs for projects demanding cross-standard equivalence.
It is the Indian Standard for mild steel plates and sheets for deep drawing/forming applications.
Typically: Carbon < 0.15%, Manganese 0.40–0.80%, Sulphur & Phosphorus < 0.04%.
Dead Soft Quality – referring to its low hardness and high bendability.
No. DSQ is softer, designed for forming, not structural strength.
Yes. Excellent weldability using standard MIG/TIG/SMAW techniques.
Yes, with proper coating (epoxy or rubber-lined) for corrosion resistance.
2 mm to 40 mm is available at HSC with mill edges or custom cuts.
HR black, pickled and oiled, shot-blasted—depending on your project.
22–26%, which makes it suitable for deep draw and folding work.
No, it is typically supplied as hot rolled plates or sheets.
Only if load is minimal. It’s primarily a forming-grade steel.
It can bend 90°–180° without cracking or loss of shape.
Yes, stamping can be done on request with traceability.
Yes. We export DSQ to UAE, Africa, Bangladesh, and more.
