S275JR Plate Cut to Size
Most S275JR plate leaves us as pieces, not full mill plates. Cutting from a full plate means you pay only for what you use, and each piece keeps the heat number of the plate it came from.
| Full & part plates | Full mill plates, halves and quarters |
|---|---|
| Rectangles & strips | To your list of finished sizes, or to a drawing |
| Circles & rings | Blanks for blind flanges, covers, tube sheets and nozzles |
| Machining allowance | State finished size and allowance; thermally cut edges are normally machined back |
| Traceability | Heat number transferred to every piece before cutting |
Send a cutting list or DXF; we nest pieces to reduce off-cut and quote per piece.

S275JR Plate Weight Chart & Calculator
Use this to budget freight and price per piece. Weight (kg) = length (m) × width (m) × thickness (mm) × 7.85.
Example: 2000 × 1000 × 10 mm
2.0 × 1.0 × 10 × 7.85 = 157.0 kg
Total weight —
| Thickness | 2000 × 1000 plate | Per m² |
|---|---|---|
| 5 mm | 78.5 kg | 39.3 kg |
| 6 mm | 94.2 kg | 47.1 kg |
| 8 mm | 125.6 kg | 62.8 kg |

S275JR Plate Price — What Decides It
Two quotes for "S275JR plate" can differ by 20% and both be fair. We quote S275JR plate per kg for full sizes and per piece for cut sizes. These six things move the price per kg, so you can compare offers like for like.
S275JR Plate Testing & Inspection
Plate goes into pressure parts and heavy sections, so it is inspected for internal soundness and flatness as well as chemistry. These tests are added to the order and reported on the certificate or as separate reports.
| Ultrasonic testing | Straight-beam UT to EN 10160 (classes S0–S3 for the body, E0–E4 for the edges) |
|---|---|
| Flatness & dimensions | Per EN 10029 (or EN 10051 for plate cut from wide strip) tables for thickness, width and length |
| Impact testing | Charpy impact test as set by the grade designation (e.g. J2 = 27 J at −20 °C; IS 2062 B0 / C sub-grades) |
| PMI | Alloy verification on each plate, or each cut piece if required |
| Third-party inspection | Witness by your inspector or agency, with an EN 10204 3.2 certificate |
UT checks the plate body along a scan grid and a band along each edge, where laminations matter most for welding.
S275JR Plate Applications
Plate is chosen for pressure-bearing walls, heavy sections and parts machined from solid. For linings, bellows and pressed parts, see S275JR sheet.
How your S275JR plate order runs
- 01Enquiry review — we confirm size, standard edition and documents against your MR or drawing.
- 02Heat selection & PMI — the mill certificate is checked and material is PMI-tested before processing.
- 03Processing — cutting to your sizes, with heat numbers transferred to every piece.

- 05Packing & dispatch — seaworthy packing from Nhava Sheva (JNPT), Mumbai, FOB or CIF, documents sent before the vessel sails.
Fabricating Heavy S275JR Plate
Shells, heads and tube sheets mean thick sections and multi-pass welds. These are the points that decide whether S275JR plate keeps its corrosion resistance after fabrication; matching filler is E7018 / ER70S-6.
General guidance only; follow your approved WPS, PQR and design code.
| Preheat | Set by thickness and carbon equivalent per your WPS and code. |
|---|---|
| PWHT | Post-weld heat treatment where the code or service requires it. |
| Joint preparation | Double-V or J-prep on heavy plate to reduce weld volume. |

S275JR plate for export
FOB / CIF · Nhava Sheva (JNPT), MumbaiS275JR plate — questions buyers ask
Is S275JR the same as EN 10025-2 S275JR?
Yes. EN 10025-2 S275JR, W.Nr 1.0044, Structural steel all refer to the same material, and plate is ordered to EN 10025-2 whichever name is on the enquiry.
What thickness counts as S275JR plate?
For S275JR, 3 mm and over as hot-rolled plate (dimensions to EN 10029); thinner gauges are rolled as hot-rolled wide strip and cut to sheet, with dimensions to EN 10051 (which also covers plate cut from wide strip up to 25 mm). Order the form that matches your drawing thickness.
What is the price of S275JR plate per kg?
It moves with steel mill prices, so a fixed list price is out of date within days. Thickness, cut size, quantity and documents also change it. Send your size and quantity and we quote the same working day.
Do you supply ultrasonically tested S275JR plate?
Yes, UT can be added to the order — to EN 10160 or the level your specification states. The UT report is supplied with the mill certificate.
Can S275JR plate be cut into circles and rings?
Yes. Blanks for blind flanges, covers and tube sheets are cut from plate to your drawing, with the heat number marked on every piece.
What machining allowance should I leave on cut plate?
It depends on the cutting method and finished tolerance. Give us the finished size and your allowance; thermally cut edges are normally machined back to sound metal.
How heavy is a S275JR plate?
Weight (kg) = length (m) × width (m) × thickness (mm) × 7.85. A 2000 × 1000 × 10 mm plate weighs about 157 kg; use the calculator on this page for your size.
What documents come with an export shipment?
An EN 10204 3.1 mill certificate (or 3.2 with a third-party inspector), commercial invoice, packing list with heat numbers, and certificate of origin. Test reports are added for any extra tests ordered.
