Yes — DSQ Plates (Dead Soft Quality Plates) are specifically designed for superior bendability and cold formability. These plates conform to IS 8917:1978 standards and are ideal for tank making, ducting, galvanizing lines, and other applications where mechanical shaping is critical. Their low carbon content, fine-grained microstructure, and controlled yield strength make them excellent for sharp bends, deep drawing, and press forming without cracking.
What Makes DSQ Plates Ideal for Press Forming?
DSQ plates are manufactured with:
- Low yield strength (~240 MPa)
- Excellent elongation (>28%)
- Fine surface finish
This unique combination ensures that DSQ steel can be shaped without stress fractures, especially in operations involving hydraulic press brakes, roll forming, or manual bending. These properties make them reliable for industries needing precise forming like tanks, pickling plants, ductwork, and plating setups.
Which Industries Prefer DSQ Steel for Forming Operations?
Some major industrial applications include:
- Acid and chemical tanks with curved structures
- Electroplating baths needing rounded interiors
- Galvanizing tanks with bent walls
- HVAC and ducting systems
- Custom-formed vessels or rectangular tanks
These industries prefer DSQ due to its controlled deformability, ensuring structural reliability post-bending.
Mechanical Properties Supporting Bending of DSQ Plates
| Property | Typical Range (DSQ) |
|---|---|
| Yield Strength | 220–260 MPa |
| Tensile Strength | 360–440 MPa |
| Elongation | Min. 28–30% |
| Bend Radius (1T–2T) | Without edge cracking |
| Standard | IS 8917:1978 |
These values enable tight-radius bends and multiple pressing operations without compromising sheet integrity.
IS 8917:1978 – The Backbone of DSQ Plate Bending Performance
IS 8917 is India’s official BIS standard for DSQ steel. It defines flat products with dead soft temper intended for cold forming. The standard ensures consistent mechanical response during pressing, rolling, or folding operations.
H6: Minimum Bend Radius of DSQ Plates
Thanks to their excellent ductility, DSQ plates can be bent at tight radii — as low as 1T, depending on thickness and surface finish. This is especially critical for circular tank bases, vessel collars, and flow ducts.
Rolling, Folding, and Hydraulic Pressing – All Possible
Whether you’re working with:
- Manual or CNC press brakes
- Hydraulic roll formers
- Rotary folding machines
DSQ steel performs reliably without microfractures, making it perfect for cylindrical, oval, or L-shaped designs.
Tips for Better DSQ Plate Formability
- Use dies with polished inner surfaces
- Ensure gradual pressing instead of sudden force
- Maintain a minimum internal radius of 1.5T for thicker plates
- Avoid heating — cold forming is sufficient in most cases
These tips extend tooling life and maintain material integrity.

Voice Search & SEO FAQs
What is the minimum bend radius of DSQ steel?
It can go as low as 1T to 2T depending on thickness and machine setup.
Is DSQ plate same as A283 Grade C for forming?
Not exactly. A283 has moderate ductility, but DSQ is better suited for tighter bends.
Are DSQ plates suitable for cold press forming?
Absolutely — that’s what they’re engineered for.
What is the IS standard for bendable DSQ plates?
IS 8917:1978 is the Indian standard for DSQ-grade cold formable steel.
Can DSQ be roll formed for ducts or pipes?
Yes, especially for HVAC ducting and square tanks.
Does Hindustan Steel test plates for bendability?
Yes, every batch undergoes bend, elongation, and edge quality tests before dispatch.
