DSQ plate stands for Dead Soft Quality steel plate, a fully killed, low-carbon mild steel product manufactured under IS 8917 and equivalent to IS 2062 Grade A or ASTM A283 Grade C. RPF Pipes & Fittings stocks this grade in ready-cut sizes for tank fabrication, galvanizing, and general engineering work, delivered worldwide. Buyers choose this plate because it bends, presses, and deep-draws without cracking, a quality that standard structural plates cannot match. Where a project requires higher tensile strength, our mild steel plates fill that gap.

Manufacturing starts with fully killing the steel. The melt is deoxidized with silicon and aluminium before casting, which removes gas porosity that would generally weaken a forming operation, and carbon stays low throughout. Mills roll the slab under controlled temperature and reduction schedules to maintain a fine and uniform grain structure, then normalizes or furnace-anneals the plate depending on purpose. This gives the finished plate a soft, ductile core capable of tight-radius bends, sometimes down to 180 degrees at zero-thickness radius, without surface cracking or the springback that plagues harder grades.

The DSQ plates chemical composition centres on tight carbon control rather than alloying strength. Typical heats hold carbon at 0.04 to 0.06 percent, manganese near 0.25 percent, and silicon, sulphur, and phosphorus each held under roughly 0.05 percent. This composition, not any coating or surface treatment, is what gives the plate its forming behaviour. Every heat gets checked by spectro analysis before dispatch, and mill test certificates travel with each consignment so a buyer can confirm the numbers against the order.

Key properties:

• » High ductility that allows cold forming and deep drawing without edge cracking
• » Excellent weldability across common arc and resistance welding processes
• » Compatible with hot-dip galvanizing, epoxy coating, and pickling lines
• » Tight dimensional tolerance suited to press tooling and jig fabrication
• » Smooth surface finish that holds coatings evenly
• » Full traceability through spectro, hydrostatic, and ultrasonic testing

Stock thickness for DSQ plate ranges from 5mm to 150mm, in widths from 1000mm to 4500mm and lengths up to 18000mm, supplied as-rolled or normalized depending on the order. Tank fabricators use it for galvanizing kettles, acid storage vessels, and cathode compartments, since the low-carbon core resists cracking under repeated thermal cycling. Outside heavy fabrication, the same DSQ steel plate turns up in auto body panels, electrical enclosure housings, and appliance shells, wherever a press line needs metal that moves through multiple draw stages without splitting.

Every plate ships against IS 8917 or the equivalent grade specified on the purchase order, backed by chemical and mechanical test reports. Each batch also undergoes hardness, flaring, and impact checks before it reaches ready stock, so material pulled from inventory carries the same consistency as a fresh mill order. Store the plate flat, off the ground, and under cover; surface rust on a dead soft grade spreads faster than it does on higher-carbon steel once moisture sets in.
