EN 10028-5 P460M Steel Plate | P460M TMCP Vessel Plate supplier
What is EN 10028-5 P460M Steel ?
P460M is the room-temperature TMCP grade in the P460 family of EN 10028-5. Buyers search EN 10028-5 P460M, P460M steel plate, 1.8826, P460M TMCP vessel plate and P460M supplier. The letter M means thermomechanically rolled fine-grain plate. This page is not P460ML1. ML1 is −40 °C. This page is not P460ML2. ML2 is −50 °C. This page is not P460N or P460NH. Those grades are EN 10028-3 normalized plate. This page is not P420M. P420M is a 420 MPa step. This page is not S460M. S460M is EN 10025-4 structural steel.
Yield is 460 MPa at ≤16 mm. Tensile is 570–720 MPa. Steel number is 1.8826. Delivery is TMCP (M), not +N. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). We buy this grade from qualified Chinese mills, check the certificate against EN 10028-5, and ship it to fabricators in the USA, Europe, Middle East, Southeast Asia, Africa and South America.
If a drawing says P460ML1, we will not ship P460M and call 460 enough. If a drawing says P420M, we will not ship P460M and call stronger automatically acceptable. Dual marking with Q460R steel plate is possible only when both books are fully met.

460 MPa comes from TMCP plus micro-alloying, not from a high-carbon melt. SHH STEEL prints heat analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.
Mechanical Properties
Buyers search P460M mechanical properties, P460M yield strength and P460M TMCP. Yield still falls with thickness.
Tensile and Yield — EN 10028-5 P460M
| Thickness (mm) | Yield min (MPa) | Tensile (MPa) |
|---|---|---|
| ≤ 16 | 460 | 570 – 720 |
| 16 – 40 | 440 | 570 – 720 |
| 40 – 63 | 430 | 550 – 720 |
| 63 – 80 | 410 | 540 – 710 |
| 80 – 100 | 400 | 530 – 710 |
| Density | 7.85 g/cm³ | 7.85 g/cm³ |
Elongation is typically 17% min on thinner plate. Room-temperature quality M does not automatically include −40 °C Charpy. If the file needs −40 °C, the grade name is P460ML1. If the file needs −50 °C, the grade name is P460ML2.
Do not quote 460 MPa yield on an 80 mm plate. Do not treat 570–720 MPa tensile as permission to stamp Q460R steel plate or SA537 Class 2 without checking both books.

TMCP 460 MPa Pressure-Vessel Service
Buyers pick P460M when a PED file wants 460 MPa TMCP plate and does not name ML impact. Search phrases such as P460M TMCP, P460M boiler plate and 1.8826 steel plate all point here.
It is not a substitute for Q460DR steel plate unless both books are met. It is not a substitute for SA841 Grade C Class 1 unless both books are met. An ASME TMCP file should name SA-841. Dual marking is possible only when chemistry, tensile, impact and delivery all fit.
SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia.
Weldability
P460M is killed TMCP fine-grain C-Mn vessel plate at 570–720 MPa tensile. Treat welding as production welding, and as PED / ASME Code welding when the equipment is a vessel.
Qualify to the applicable code. Consumables must match the 460 MPa / 570–720 MPa band. A P420M procedure is the previous family. A procedure written for SA516 Grade 70 may be light on strength. Heat input on TMCP plate should stay controlled so the rolled grain is not coarsened in the HAZ. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.
Heat Treatment and Delivery Condition
Usual delivery from SHH STEEL is thermomechanically rolled EN 10028-5 P460M (M). This is not +N from EN 10028-3 and not QT from EN 10025-6.
If the vessel will see PWHT, say so. TMCP properties can move after a long stress-relief cycle. Simulated PWHT on test coupons is worth naming. Extra simulation, 3.2 hold points or special NDE add time. Plan about two months when those extras are on the order.
The certificate lists EN 10028-5 P460M; 1.8826; heat number; cast analysis; product analysis when ordered; tensile to the correct thickness column; M / TMCP; impact only when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.
Dimensions
Usual supply range from SHH STEEL for P460M TMCP vessel plate:
- Thickness: commonly 6 mm – 80 mm, thicker by mill agreement
- Width: 1500 mm – 4000 mm
- Length: 3000 mm – 12000 mm
Normalized 460 fine-grain plate belongs on EN 10028-3. Structural TMCP belongs on EN 10025-4. QT 460 / 690 plate belongs on EN 10025-6.
Tolerances
Dimensional limits for EN 10028-5 P460M follow EN 10028-1 and EN 10029 unless the purchase order names another table. Class A is the usual mill default for P460M TMCP vessel plate. Class B, Class C or Class D is supplied only when written. Do not apply ASTM A36 structural tolerances to a PED 460 MPa TMCP plate without writing them. When dual-named against SA841 Grade C Class 1, write whether EN 10029 or SA-20 governs the minus on thickness.
Typical thickness tolerance idea for P460M (EN 10029 Class A, reference)
| Nominal thickness (mm) | Class A minus (mm) | Class A plus (mm) |
|---|---|---|
| 6 – 8 | −0.4 | +0.8 |
| 8 – 15 | −0.5 | +0.9 |
| 15 – 25 | −0.6 | +1.0 |
| 25 – 40 | −0.7 | +1.1 |
| 40 – 80 | −0.8 | +1.2 |
Width on 1500–4000 mm plate is commonly held to about ±20–25 mm unless the mill quote names a tighter extra. Length on 3000–12000 mm plate is commonly held to about +50 / 0 mm or ±25 mm by mill practice. Flatness follows EN 10029 Class N unless Class S is written. Edge condition is mill edge or cut edge as ordered. If the vessel calculation used minimum thickness after corrosion, write the allowed minus on the RFQ. SHH STEEL will not assume Class B or a zero-minus extra on P460M unless the order says so.
Supplementary Requirements
Charpy details. P460M does not assume −40 °C. Write temperature and orientation if impact is required.
Product analysis. Add this when the destination file wants finished-plate chemistry.
Simulated PWHT. When the equipment will be stress-relieved.
NDE. EN 10160 or the named UT class.
Third-party. EN 10204 3.2 when written.
Applications
| Industry | Typical components |
|---|---|
| PED high-strength drums | EN 10028-5 P460M shells |
| TMCP heat-exchanger shells | P460M courses |
| Room-temp 460 MPa vessels | P460M plate from SHH STEEL |
| Dual-certified export | P460M / Q460R steel plate when both books fit |
P460M is the plate for a file that wants 460 MPa TMCP steel and does not name ML impact. It is the wrong plate for a winter tank at −40 °C. That work is P460ML1. It is the wrong plate for a normalized EN 10028-3 file. That work is P460NH.

Why Choose SHH STEEL
Experience on this grade is simple: keep the letter after P460. M, ML1 and ML2 are three different purchase orders, and none of them is P460NH. SHH STEEL as a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) prices P460M from first-line mills, reports 1.8826 chemistry, records TMCP, and issues 3.1 as standard or 3.2 when specified.
We keep the grade on the order. P460M is not P420M. P460M is not P460ML1. P460M is not P460NH. P460M is not Q345R steel plate. If the drawing says P460ML2, we will not ship P460M and call TMCP close.
