Home > Our Products > DSQ (Dead Soft Quality) Steel Plates
Whether you’re building galvanizing tanks, chemical storage vessels, or precision-formed ducts, the choice of plate material determines the performance and longevity of your entire structure. DSQ steel, known for its low carbon content and exceptional formability, is the go-to steel grade for manufacturers demanding dead-soft consistency, surface finish, and cold bending ability. At Hindustan Steel Corporation, we supply and stock DSQ plates in standard and custom sizes, ready for dispatch across India and export markets.
Discover the right grade, thickness, and size for your project—whether you’re sourcing in bulk for pickling plants or precision-cut components for electroplating.
DSQ stands for Dead Soft Quality — a specialized category of mild steel plate characterized by its low carbon content, excellent ductility, and superior formability. Unlike high tensile or structural-grade steels, DSQ plates are engineered to remain soft, smooth, and cold-workable, making them ideal for applications where bending, pressing, or drawing is required without cracking or losing surface finish.
This steel is commonly used in industries that demand acid resistance, zero surface stress, and tight dimensional tolerance, especially when constructing tanks, ducts, and chemical processing systems. Most DSQ plates comply with Indian Standard IS 2062 Grade A or equivalent ASTM A283 Grade C specifications and are available in thicknesses ranging from 2mm to 100mm.
In short: If your job requires steel that bends without breaking, welds cleanly, and handles corrosive chemicals, DSQ plates are the right fit.
DSQ (Dead Soft Quality) steel plates are widely trusted in industries where formability, corrosion resistance, and zero surface stress are crucial. Their consistent low-carbon makeup and dead-soft temper make them a preferred material for fabrication, chemical handling, and surface-treated structures.
Here are the top industrial applications of DSQ plates:
Used extensively in hot-dip galvanizing plants for fabricating tanks that resist acid fluxes and maintain dimensional stability during thermal cycling.
DSQ plates are compatible with a range of acids and alkaline substances, making them ideal for chemical storage containers, drums, and bins.
Commonly used for plating tanks, liners, and structural enclosures due to their corrosion resistance and ease of welding/forming.
DSQ plates are ideal for air duct fabrication, HVAC applications, and sheet-formed vessels requiring smooth surface flow and minimal internal stress.
Utilized by OEMs and contractors for custom tanks, tubs, brackets, trays, and more — where press-formed shapes and acid resistance are a priority.
For chemical-resistant vats, dye tanks, and acid-proof structural trays used in wet processing units.
DSQ plates are ideal for air duct fabrication, HVAC applications, and sheet-formed vessels requiring smooth surface flow and minimal internal stress.
Used in enclosed process chambers, bins, or washdown environments where hygiene and surface softness are essential.
carbon plates protect your machinery, bottom-line, and team.
DSQ (Dead Soft Quality) steel plates don’t belong to a single standard but are classified based on performance characteristics like deep drawability, acid resistance, and forming capability. Various industries refer to DSQ using functional equivalents or loosely associated standards to ensure procurement clarity.
Here’s how DSQ aligns with commonly accepted grades:
| Standard | Equivalent Grade | Remarks |
| Indian Standard | IS 2062 Grade A / E250 (Soft condition) | Matches mechanical softness with better ductility |
| ASTM | A283 Grade C | Used as a comparative standard for chemical tanks |
| EN Standard | EN 10025 S235 (non-structural use) | Very close in mechanical softness when annealed |
| Custom Rolling | Soft annealed carbon steel | Dead Soft state is often achieved via custom annealing |
| Type | Description | Common Thickness |
| DSQ for Tank Fabrication | Optimized for bending/forming into large radius vessels | 5mm–30mm |
| DSQ Acid-Resistant Plates | Surface-prepared for resistance to pickling and galvanizing acids | 8mm–50mm |
| DSQ for Electroplating Units | Smooth-surface plates for internal linings | 4mm–20mm |
| DSQ for Custom OEM Projects | Available in cut-to-size sheets for custom fabrication | On-demand |
Also available in hot-rolled sheets, coils, and strip forms in A36, IS 1079, IS 2062, or ST52.3, depending on end-use.
DSQ plates are not defined by high strength but by exceptional softness, ductility, and formability—making them the ideal material for applications like galvanizing tanks, pickling lines, and chemical containers where bending, deep drawing, and acid resistance are key.
| Property | Value Range | Remarks |
| Yield Strength | 240 – 280 MPa | Soft annealed for deep drawing applications |
| Tensile Strength | 370 – 470 MPa | Lower strength helps with press forming |
| Elongation | ≥ 28% | Excellent ductility for bending/forming |
| Hardness (BHN) | 120 – 160 BHN | Measured under annealed condition |
| Formability | Dead Soft | Ideal for cylindrical tank rolling and folds |
| Element | Content (%) |
| Carbon (C) | 0.15 max |
| Manganese (Mn) | 0.50 – 0.90 |
| Sulphur (S) | 0.040 max |
| Phosphorus (P) | 0.040 max |
| Silicon (Si) | 0.05 – 0.30 |
Note: Composition varies slightly depending on the source standard (IS, ASTM, or Custom MTC-based).
| Parameter | Range Available |
| Thickness | 3 mm to 100 mm |
| Width | 1000 mm to 2500 mm |
| Length | 2500 mm to 12500 mm |
| Cut Sizes | As per drawing |
| Finish | Mill finish, Sheared edge, Acid-cleaned available |
DSQ plates are often project-specified—compliance is typically validated by Mill Test Certificate (MTC) and tank design drawings. Buyers should always verify if DSQ grades meet acid resistance, drawing depth, and stress relief criteria before procurement
DSQ (Dead Soft Quality) Steel Plates may not have a globally unified standard like structural steels, but they comply with select Indian and international specifications that focus on soft, formable, and acid-resistant applications.
| Standard Code | Equivalent / Description |
| IS 2062 Grade A | Indian structural steel standard (used for DSQ base) |
| ASTM A283 Grade C | Soft steel plate suitable for general fabrication |
| EN 10025 S235JR | European equivalent (low carbon, soft forming steel) |
| SAE 1010 / 1008 | Soft drawing-quality carbon steels (USA standard) |
Most reputed DSQ plate manufacturers and stockists, including HIND, supply plates with:

Choosing the wrong DSQ (Dead Soft Quality) plate isn’t just a technical error — it can lead to fabrication delays, tank failures, or acid leaks. Here’s how to avoid costly mistakes and get the right product the first time:
Reality: Not all “DSQ” plates are dead-soft in practice. Many sellers stock IS 2062 Grade A or E250 and label them as DSQ — which often have higher yield strength than required.
✅ What to Do: Ask for formability test results or ensure compliance with DSQ-specific stress ranges.
DSQ plates are used for press-formed vessels, so surface finish and bend tolerance matter.
✅ What to Do: Request samples or insist on a bend-test certificate (e.g., 180° bend test) if your job involves curved tank bottoms or duct shapes.
Many local traders offer DSQ plates without origin traceability or quality certification.
✅ What to Do: Choose a certified manufacturer-backed stockist (like us) offering MTC, ISO, and IBR documents.
Using 6mm plates where 10mm is needed (or vice versa) affects project stability and cost.
✅ What to Do: Match plate thickness, length, and soft-pressable range with tank design specs and acid storage norms.
Generic MS plates sold at DSQ prices lead to poor ROI.
✅ What to Do: Verify steel origin, DSQ certification, and get competitive quotes from vendors with proven industry presence.
Steel delivery timelines affect entire project Gantt charts. Always confirm availability, lead time, and cut-to-size options upfront.
Always send us your spec sheet or past invoice if unsure. We'll suggest the best-fit plate — technically and commercially.
Real DSQ sheets usually fall between 250–270 MPa.
