DSQ Plate as per Indian Standard

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.

What is DSQ Plate as per Indian Standard?

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:

  • Ultra-low carbon content (typically < 0.15%)
  • High elongation (22–26%)
  • Low yield strength (~240 MPa)
  • Soft temper with excellent cold bendability

It is not meant for load-bearing, but is indispensable for chemical tank linings, galvanizing plants, and formed vessels.

Applications of DSQ Steel as per IS 8917:1978

DSQ plates produced under Indian standards are widely used in:

  • Acid-resistant tanks and chemical storage units
  • Pressed components and shaped vessels
  • Ducts, bends, trays, and covers in galvanizing/pickling plants
  • General fabrication requiring tight folds and smooth shaping
  • Electroplating enclosures and acid process containers
  • Formed auto parts (where IS 1079/513 isn’t thick enough)

Note: These plates are usually purchased in soft-annealed or normalized condition, ready for shaping without cracking or edge stress.

Mechanical Properties as per Indian Standard for DSQ Plates

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.

DSQ Plate Specification as per IS 8917:1978

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:

  • Standard No.: IS 8917:1978
  • Steel Type: Dead Soft Mild Steel (Non-structural)
  • Applications: Forming, pressing, drawing, non-load-bearing vessels
  • Supply Condition: Soft-annealed / Normalized
  • Thickness Tolerance: As per IS 1852 or customer spec
  • Marking: Grade, batch, heat no., HSC brand

HSC ensures full IS 8917 adherence, and also offers lab verification reports on request.

Thickness, Size & Dimensional Range

We supply DSQ plates per Indian standard in the following configurations:

  • Thickness: 2 mm to 40 mm
  • Width: 1000 mm to 2500 mm
  • Length: 2500 mm to 6300 mm
  • Flatness Tolerance: As per IS 1852
  • Edge Type: Mill edge / Sheared / Bevelled
  • Finish: Hot rolled (HR), Pickled, Oil-coated, or Shot blasted

Custom lengths and CNC-blanked cut-to-size plates are available for OEMs and tank builders.

Temper, Heat Treatment & Supply Conditions

DSQ plates under IS 8917 are typically delivered in softest possible condition. At Hindustan Steel Corporation, we offer:

  • Soft Annealed (Dead Soft) – For deep drawing and forming
  • Normalized – For shape consistency after stress-relieving
  • Pickled & Oiled – For improved surface finish in acid-prone environments
  • Shot Blasted (optional) – On demand for paint-ready finishes

We also supply dual-certified DSQ + IS 2062 E250A material for projects requiring soft formability plus structural compliance.

Fabrication Tips – Cutting, Welding, Bending

DSQ steel plates per Indian Standard are very easy to work with. Here’s a process breakdown:

  • Cutting: Plasma, oxyfuel, laser — minimal edge hardening
  • Welding: MIG/TIG/SMAW — no preheating required
  • Forming/Bending: Ideal for 90° to 180° press work
  • Punching & Notching: No microcrack or edge tear risk
  • Chemical Lining: Compatible with acid-resistant epoxy coatings

Always verify forming direction when rolling or folding DSQ sheets — grain structure affects bend radius.

Why Buy DSQ Steel from Hindustan Steel Corporation?

We’re among India’s few stockholders who specialize in DSQ material as per IS 8917, not just commercial “soft plates.”

Why HSC:

  • Consistent BIS-aligned chemistry and temper
  • In-stock thickness from 2 mm to 40 mm
  • Trusted supplier to galvanizing units, pickling plants, ducting contractors
  • MTC + Lab Certificate + Custom Temper Stamp available
  • Fast delivery across India and bulk export orders accepted

We understand DSQ is not a “generic soft plate” — we deliver true dead-soft material per Indian standards.

Related Standards and Alternatives

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.

Buyer Guide – When Should You Choose DSQ Plate per Indian Standard?

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.
