Looking for steel plates that offer exceptional bendability, clean surfaces, and tight radius forming? DSQ (Dead Soft Quality) plates by Hindustan Steel Corporation are the trusted choice for ducting, hoppers, chemical funnels, and deep-formed vessels. Made as per IS 8917:1978, our DSQ plates are engineered for smooth press forming, roll forming, and manual duct fabrication without cracks or spring-back.
With low carbon content, high elongation (25%+), and scale-free surfaces, these plates ensure precise forming for critical air flow ducts, pressure-less vessels, and FRP-lined tanks in industries like HVAC, plating, galvanizing, and process plants.
We supply cut-to-size DSQ sheets and shells to OEMs, EPCs, and tank fabricators pan India and globally.
DSQ stands for Dead Soft Quality, a category of mild steel that is cold-formable, low in hardness, and excellent for deep drawing or pressing. Unlike structural steel grades like IS 2062, DSQ does not resist deformation – making it ideal for ductwork, curved shapes, tank ends, and special form vessels.
In formed vessels and ducting, DSQ ensures:
At Hindustan Steel Corporation, we serve companies manufacturing:
Our DSQ steel plates are also suitable for metal forming training institutes, press tools, and rolling units where precise bending and forming tests are conducted.
| Property | Value / Range |
|---|---|
| Yield Strength | 200 – 250 MPa |
| Tensile Strength | 300 – 410 MPa |
| Elongation | ≥ 25% |
| Hardness | < 100 BHN |
| Thickness Range | 2 mm – 16 mm |
| Surface Finish | Smooth, lamination-free |
| Tolerance | As per IS 8917 or custom |
Note: We also provide custom rerolled DSQ plates for high ductility requirements with full test certificates.
DSQ steel plates are governed by IS 8917:1978, a Bureau of Indian Standards (BIS) code designed specifically for cold forming applications. It is not a structural steel and differs from IS 2062 in both chemistry and elongation.
Conforming to IS 8917 ensures:
We stock DSQ plates in compliance with IS 8917, with optional 3rd party inspection.
Hindustan Steel Corporation offers:
We supply in:
DSQ plates are non-heat-treated, low carbon steels ideal for cold forming. Their soft metallurgical state enables:
