DSQ Plates for Pickling Plant Construction – IS 8917 Steel for Acid Lines

Hindustan Steel Corporation supplies DSQ plates as the preferred mild steel material for constructing acid pickling plants, particularly hydrochloric acid (HCl) and sulphuric acid-based lines. These plates conform to IS 8917:1978 – the Indian Standard for deep drawing and formable carbon steel. While DSQ is not inherently corrosion-resistant, it forms a highly weldable, bendable, and stable base metal for rubber-lined, FRP-lined, or epoxy-coated acid tanks, channels, and process pits.

What Makes DSQ Plates Ideal for Acid Pickling Line Construction?

Pickling operations require tanks, ditches, and reactors that:

  • Can be fabricated in custom shapes and depths
  • Withstand mild mechanical load and acid exposure
  • Support long-term chemical coating (rubber, FRP)
  • Comply with Indian and global safety standards

DSQ material allows tight bending and clean welding, making it ideal for tank shells, overflow weirs, sloped channels, and drain lines within a pickling plant.

Industrial Applications – Where DSQ is Used in Pickling Plants

Our DSQ steel plates are used in:

  • HCl and sulfuric acid pickling tanks
  • Acid circulation channeling systems
  • Overhead degreasing hoods (with lining)
  • Settling pits and acid neutralization vessels
  • Acid drainage sumps
  • Tank overflow trays and collection channels
  • Furnace component trays (low heat zones)

Mechanical & Formability Properties of DSQ Plates

Property Typical Value
Yield Strength Min. 240 MPa
Tensile Strength 360 – 410 MPa
Elongation 22% min
Weldability Excellent – no preheating required
Bend Radius As low as 1T
Hardness (approx.) 130–160 BHN
Grade Type Dead Soft Quality (DSQ)

These properties ensure clean formability for dished ends, cone-shaped flow outlets, and custom tank geometries.

Indian Standard Compliance – IS 8917:1978 for DSQ Plate Material

All DSQ plates supplied by Hindustan Steel Corporation meet the norms laid out under IS 8917:1978, the BIS standard for Dead Soft Quality (DSQ) steel. This ensures:

  • Exceptional ductility for cone, dome, and sloped tank shapes
  • Compatibility with acid-resistant linings
  • Easy cutting and welding without special pre-treatment
  • Uniform base surface for rubber / FRP bonding

We offer material test certificates (MTCs) with every supply as per IS norms and customer-specific QA standards.

Plate Thickness, Width & Length for Pickling Projects

We offer cut-to-size DSQ plates in the following standard and custom dimensions:

  • Thickness Range: 3 mm to 25 mm
  • Standard Widths: 1250 mm / 1500 mm / 2000 mm
  • Standard Lengths: 2500 mm / 5000 mm / Custom as required
  • Edge Finish: Sheared or Mill edge
  • Tolerance: As per IS 8917 or client-specified

Custom sizes are manufactured for special projects like deep pit tanks, long acid channels, or suspended degreasing systems.

Can DSQ Steel Withstand Acid? Lining Compatibility Explained

DSQ steel is not corrosion-resistant on its own, but that’s exactly why it’s chosen as the base plate in lined equipment. Its strength lies in its compatibility with:

  • Rubber Lining (Natural/Synthetic): Ideal for HCl pickling lines
  • FRP & GRP Lining: For structural acid ducting and overhead enclosures
  • Epoxy Coatings: For drain trays and splash zones
  • Lead Lining: Used in legacy sulphuric acid tank applications

DSQ forms a stable, uniform, crack-free surface for acid-resistant linings to adhere securely, which is vital for plant longevity and safety.

Welding & Fabrication Guidelines for Pickling Tanks

  • Welding: DSQ requires no preheat or PWHT, works with standard MIG/TIG setups
  • Bending: Achievable up to 1T radius in 6 mm or thinner sheets
  • Rolling: Smooth, crack-free rolling for circular tank shells
  • Cutting: Easy plasma or laser cutting; low slag generation
  • Machining: Good machinability for fitment grooves or lining-ready surfaces

Our sheets are also used in slotted acid collection floors and multi-bay degreasing tanks, where modular welding is required.

We understand the challenges of acid line corrosion, and that’s why we support your entire lifecycle – from project start to post-lining inspection.

Other Grades Similar to DSQ for Chemical Tanks

Grade Standard Usage
IS 2062 Grade A BIS General structural use (not dead soft)
ASTM A283 Grade C ASTM Pressure vessels, mild structures
ASTM A36 ASTM Moderate strength, tank fabrication
IS 1079 CR Sheets BIS Cold rolled tanks and linings
S275JR EN Standard Lined equipment with mechanical stress

Still, DSQ remains unmatched for dead soft drawability in non-load-bearing lined applications like pickling tanks and pits

Buyer Tips – How to Select DSQ Plate for Acid Tank Projects?

Before you place an order, check these:

  • Confirm IS 8917 compliance – not all suppliers offer BIS-certified DSQ
  • Ensure your tank designer specifies correct thickness and rolling direction
  • Match your plate surface to lining compatibility (rubber, FRP, lead, etc.)
  • Ask for bend and drawability tests for conical tanks
  • Request cut-to-size service to reduce fabrication loss
  • Crosscheck mill test certificates for batch-wise traceability

Avoid mild steel substitutes in critical applications – they may crack during bending or compromise lining adhesion.

Every plate from Hindustan Steel Corporation comes with:

  • Mill Test Certificate (MTC) as per IS 8917:1978
  • Custom stamping with heat number, batch ID & trace code

  • Pre-dispatch visual and flatness inspection
  • Packing as per export-grade safety and sea-worthiness

On request, we provide third-party inspection (TPI) from SGS, BV, or Lloyds.15 Buyer-Focused FAQs (SEO + Voice Search + AEO)

FAQs Pickling Plants

DSQ plates are manufactured as per IS 8917:1978, which specifies chemical and mechanical properties suitable for forming and lining.

DSQ steel itself is not acid-resistant but serves as a backing plate for acid-resistant linings like rubber, FRP, or epoxy.

Typically, 6 mm to 16 mm thick plates are used for vertical tanks, while thinner sheets (3–5 mm) are used for tray floors and channels.

DSQ plates must pass a 180° bend test without cracks, as per IS 8917 specifications

No. DSQ is a softer, more ductile version of low-carbon steel, designed specifically for formability in lined applications.

DSQ is better for acid tank lining due to superior formability; IS 2062 is used for structural parts.

DSQ stands for Dead Soft Quality steel

No. DSQ is not meant for pressure applications; it’s ideal for atmospheric storage tanks

Low carbon (typically <0.15%), with controlled manganese and silicon content for ductility and weldability.

Check for IS marking, heat number, bend test report, and surface uniformity. We always supply MTC for traceability.

Yes, we offer cut-to-size DSQ plates for hassle-free tank fabrication and reduced wastage.

We only supply steel – DSQ base plates ready for lining. We don’t do rubber/FRP lining ourselves.
