DSQ Plates for Acid & Chemical Storage Tanks – Fabrication-Ready, Acid-Coatable Mild Steel
Need a steel plate that bends cleanly, welds smoothly, and withstands acid contact after lining? DSQ (Dead Soft Quality) Plates, as supplied by Hindustan Steel Corporation, are a trusted choice for chemical and acid storage tank fabrication—used in pickling plants, plating facilities, acid circulation tanks, and effluent treatment units.
DSQ plates offer a non-structural, ultra-soft grade of steel ideal for tanks that are to be rubber-lined, epoxy-lined, or FRP-coated for handling corrosive chemicals like HCl, H₂SO₄, HNO₃, NaOH, or ZnCl₂.
Why Use DSQ Plates for Acid Handling and Chemical Storage?
Acid and chemical tanks require plates that can be:
DSQ Plates, aligned with IS 8917:1978, are designed for press-formed non-pressure vessels—and are far superior to structural grades like IS 2062 when it comes to chemical tank construction.
Our DSQ plates are trusted by OEMs and plant fabricators across:
Most clients rubber line or epoxy coat these tanks using our DSQ plate shells for 10+ year durability.
| Property | Value / Relevance |
|---|---|
| Yield Strength | ~240 MPa – ideal for folding |
| Elongation | 22–26% – allows 180° press bends |
| Hardness | ~120 BHN – soft enough to avoid cracking |
| Surface Finish | HR, shot-blasted, or pickled on request |
| Lining Compatibility | Epoxy, FRP, glass flake, rubber |
| Stress Resistance | Low internal stress; ideal for acid tanks |
| Corrosion Tolerance | Provided via lining, not base steel |
DSQ plates don’t resist acid directly, but they’re the perfect substrate for chemical-resistant coatings due to their uniform surface and stress-free base metal.
DSQ plates used for acid or chemical storage tank fabrication must adhere to:
IS 8917 DSQ steel is preferred due to:
We can also provide DSQ + ASTM A283 Gr C dual-certified plates for international tank projects.
Depending on tank size, lining type, and fluid, we recommend:
| Component | Suggested DSQ Thickness |
|---|---|
| Cylindrical tank wall | 4 mm – 10 mm |
| Rectangular base shell | 6 mm – 12 mm |
| Baffles, bracing | 3 mm – 6 mm |
| Lining base plate | 3 mm – 5 mm |
| Overflow chambers | 4 mm – 8 mm |
Available Sizes:
We offer laser-ready blanks, radius plates, and edge-prepped shells for tank assembly.
DSQ’s soft structure allows full forming without heat cracking or flange tearing:
Tanks can be fabricated and lined within 3–5 working days with DSQ plate, without distortion or post-weld warping.
| Parameter | DSQ Plate | IS 2062 E250 |
|---|---|---|
| Bending Ease | Excellent | Moderate |
| Lining Compatibility | Smooth surface | Slight hardness |
| Crack Risk on Press | None | Moderate |
| Cost | Affordable | Slightly higher |
| Stress Zones after welding | None | Present |
| Standard | IS 8917 | IS 2062 |
At Hindustan Steel Corporation:
We also supply IS 8917 + MTC, third-party inspection reports, and coating-ready surface finish.
You may also consider:
| Product / Grade | Use Case |
|---|---|
| ASTM A283 Grade C | Global alternative to DSQ |
| HIND DSQ Tank Grade | HSC’s custom DSQ plate for chemical tanks |
| SS 316L (liner) | For permanent acid tanks (inner shell) |
| DSQ + FRP Coated | For high-acid or degreasing units |
| DSQ for Pickling Lines | For large immersion tanks (HCl-based) |
We also supply Gaskets, baffle plates, overflow lids, and pre-shaped base rings if required.
Hindustan Steel Corporation exports DSQ plates for acid tanks and chemical process vessels to:
Export Packaging Options:
We support full technical file dispatch, MSDS, and third-party inspection prior to delivery.
If your plant handles corrosive or volatile chemicals, here’s what to consider:
| Factor | Recommended Grade |
|---|---|
| Epoxy-coated mild steel tank | DSQ Plate (IS 8917) |
| Rubber-lined acid tank | DSQ (3 mm – 6 mm) |
| Global standard compliance | ASTM A283 Grade C |
| High-temp chemical zones | DSQ + FRP lining |
| Long-term acid resistance | DSQ + glass flake coating |
| Direct acid contact (no lining) | SS 316L or SS 904L |
Always match DSQ with the right liner. The plate provides shape; the liner gives corrosion resistance.
Each order of DSQ plates for acid storage includes:
Ideal for turnkey tank orders, export jobs, and government tenders requiring technical documentation.
No. It’s not acid-resistant on its own—it must be lined.
It’s the Indian standard for mild steel used in deep drawing and forming applications.
5–10 mm, depending on tank size and location.
Yes, with proper FRP or epoxy lining.
Yield: ~240 MPa, Elongation: 22–26%, Soft temper.
Yes. It offers excellent weldability without preheating.
No. DSQ is for non-pressure applications only.
Hot-rolled, pickled, or shot-blasted—depending on need.
