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.
Pickling operations require tanks, ditches, and reactors that:
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.
Our DSQ steel plates are used in:
| 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.
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:
We offer material test certificates (MTCs) with every supply as per IS norms and customer-specific QA standards.
We offer cut-to-size DSQ plates in the following standard and custom dimensions:
Custom sizes are manufactured for special projects like deep pit tanks, long acid channels, or suspended degreasing systems.
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:
DSQ forms a stable, uniform, crack-free surface for acid-resistant linings to adhere securely, which is vital for plant longevity and safety.
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.
| 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
Hindustan Steel Corporation supplies DSQ plates to leading OEMs and contractors across:
We have supported multiple turnkey pickling plant installations with DSQ plate supply for acid tanks, drain channels, neutralization pits, and structural steel supports.
Before you place an order, check these:
Avoid mild steel substitutes in critical applications – they may crack during bending or compromise lining adhesion.
Every plate from Hindustan Steel Corporation comes with:
On request, we provide third-party inspection (TPI) from SGS, BV, or Lloyds.15 Buyer-Focused FAQs (SEO + Voice Search + AEO)
DSQ plate (Dead Soft Quality) is a steel plate with high ductility, used as a base material for rubber or FRP-lined acid tanks in 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.
Yes, we maintain ready inventory of IS 8917 DSQ plates in common sizes and thicknesses.
For container loads, we can dispatch within 7–10 working days after confirmation, with full documentation and packing.
