EN 10028-2 7CrMoVTiB10-10 Steel Plate | T24 2.25Cr-Mo-V-Ti-B Vessel Plate
What is EN 10028-2 7CrMoVTiB10-10 Steel?
7CrMoVTiB10-10 is the titanium-boron 2.25Cr-Mo-V grade in EN 10028-2. Buyers almost never type the full EN name first. They type T24, T24 steel plate, 7CrMoVTiB10-10, 1.7378 and T24 2.25Cr-Mo-V-Ti-B vessel plate. All of those names belong on this page. T24 is the market / tube-family name. 7CrMoVTiB10-10 is the EN steel name. 1.7378 is the steel number.
This is not 10CrMo9-10. 10CrMo9-10 is 2.25Cr-1Mo without vanadium, titanium and boron. This is not P91. P91 is 9Cr-1Mo-V-Nb. This is not T23. T23 is a different tungsten-vanadium family. Chromium stays in the 2.20–2.60% band. Molybdenum stays near 1%. Vanadium, titanium and boron are mandatory. That package is why T24 was developed for high-temperature water-wall and header work, and why welding cannot be copied from a Grade 22 procedure.
Yield on the EN plate table is in the 450 MPa class at the usual thin-plate column. Tensile is 580–760 MPa. Tube product T24 often sits at a higher yield in ASME SA-213. Plate and tube are not automatic twins. Dual marking is possible only when both books are fully met. Delivery is usually normalized and tempered. Write the route. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) supplying this grade to the USA, Europe, Middle East, Southeast Asia, Africa and South America.
Do not ship SA387 Grade 22 Class 2 against a T24 drawing. Grade 22 has no Ti-B-V set of this type. Do not ship SA387 Grade 91 Class 2 and call 9Cr better. The ASME talk grades around this chemistry are SA832 Grade 22V and SA542 Type C Class 4. Dual marking is possible only when chemistry, tensile, hardness, impact and heat treatment all fit.

This plate sits in pressure vessel steel plates. 2.25Cr-1Mo comparisons belong on ASME SA387. Cr-Mo-V comparisons belong on ASME SA832 and ASME SA542.
Chemical Composition
Cast analysis follows EN 10028-2 Table 1. Product analysis follows EN 10028-1 when ordered. People who search T24 chemical composition, 7CrMoVTiB10-10 chemistry and 1.7378 composition want titanium and boron on the certificate, not only chromium and molybdenum.
Cast Analysis and Product Analysis — EN 10028-2 7CrMoVTiB10-10 (1.7378)
| Element | Cast Analysis (%) | Product Analysis, when ordered (%) |
|---|---|---|
| Carbon (C) | 0.05 – 0.10 | 0.04 – 0.12 |
| Silicon (Si) | 0.15 – 0.45 | 0.10 – 0.50 |
| Manganese (Mn) | 0.30 – 0.70 | 0.25 – 0.78 |
| Phosphorus (P), max | 0.020 | 0.025 |
| Sulfur (S), max | 0.010 | 0.013 |
| Nitrogen (N), max | 0.010 | 0.012 |
| Aluminum (Al), max | 0.020 | 0.025 |
| Chromium (Cr) | 2.20 – 2.60 | 2.10 – 2.70 |
| Molybdenum (Mo) | 0.90 – 1.10 | 0.85 – 1.15 |
| Vanadium (V) | 0.20 – 0.30 | 0.18 – 0.33 |

| Boron (B) | 0.0015 – 0.0070 | 0.0010 – 0.0080 |
| Nickel (Ni), max | 0.30 | 0.35 |
Carbon is low on purpose. Titanium and boron are the grade. Nitrogen and aluminum stay limited because they fight the titanium-boron effect. If a mill certificate shows 2.25Cr-1Mo and no Ti-B-V, that plate is 10CrMo9-10, not T24. SHH STEEL reports cast analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.
Mechanical Properties
Buyers search T24 mechanical properties, 7CrMoVTiB10-10 yield strength and T24 tensile strength. EN plate values and ASME T24 tube values sit in the same family. They are not copy-paste identical. Write the product form.
Tensile and Yield — EN 10028-2 7CrMoVTiB10-10 / T24 plate
| Item | Typical EN plate value | Note |
|---|---|---|
| Yield / Rp0.2 | 450 MPa class | Thickness column applies |
| Tensile Rm | 580 – 760 MPa | Confirm on MTC |
| Elongation | about 16–18% min | Thinner plate |
| Hardness | controlled after HT | Write if the file uses it |
| Density | 7.85 g/cm³ | 7.85 g/cm³ |
Impact at 0 °C, 27 J, is the usual option when the order names it. Hardness after heat treatment matters because T24 can run hard if tempering is short. Elevated-temperature proof strength is why the grade exists. Ask for that table when the vessel calculation uses design temperature.
Do not quote 450 MPa yield on every thickness. Do not treat 580–760 MPa tensile as permission to stamp SA387 Grade 22 Class 2 or SA832 Grade 22V without checking both books.

T24 2.25Cr-Mo-V-Ti-B Pressure-Vessel Service
Buyers pick 7CrMoVTiB10-10 / T24 when the file wants 2.25Cr-1Mo with vanadium, titanium and boron for higher-temperature water-wall, collector and thin-wall high-temp service. Search phrases such as T24 boiler plate, T24 pressure vessel plate, 7CrMoVTiB10-10 steel plate and 1.7378 steel plate all point here.
T24 exists because Grade 22 runs out of strength in some high-temperature thin-wall designs. That does not mean T24 replaces every Grade 22 file. A hydroprocessing vessel written to SA387 Grade 22 Class 2 still wants Grade 22 unless the designer changes the book. A 9Cr file written to SA387 Grade 91 Class 2 is a different family.
SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia. The purchase is not limited to China, Hong Kong or Singapore.
Weldability
7CrMoVTiB10-10 / T24 is not a Grade 22 weld. Treat welding as production welding, and as PED / ASME Code welding when the equipment is a vessel.
Qualify to the applicable code. ASME dual-name work uses ASME Section IX. Consumables must be T24-matching consumables, not Grade 22 and not P91. Preheat, hydrogen control and the PWHT window belong in the procedure. T24 has a reputation in the industry for heat-affected-zone sensitivity when the procedure is copied from Grade 22. That is a qualification issue, not a warehouse issue. 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 normalized and tempered EN 10028-2 7CrMoVTiB10-10. Buyers who search T24 heat treatment, T24 PWHT or 7CrMoVTiB10-10 NT are asking for this control.
If the vessel will see PWHT, write the temperature window. Test coupons then follow a simulated cycle. Hardness after simulated PWHT is worth naming on this grade. 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 10028-2 7CrMoVTiB10-10; T24 when the order uses that name; 1.7378; heat number; cast analysis including V, Ti and B; product analysis when ordered; tensile to the correct thickness column; +NT; hardness when ordered; impact when ordered; elevated-temperature values when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2.
Dimensions
Usual supply range from SHH STEEL for T24 2.25Cr-Mo-V-Ti-B vessel plate:
- Thickness: commonly 6 mm – 80 mm, thicker by mill agreement
- Width: 1500 mm – 3000 mm
- Length: 3000 mm – 12000 mm
Plain 2.25Cr-1Mo belongs on 12Cr2Mo1R steel plate. 1Cr-0.5Mo belongs on 15CrMoR steel plate. Carbon vessel plate belongs on Q345R steel plate.
Tolerances
Dimensional limits follow EN 10028-1 and EN 10029 unless the order names another tolerance table. Do not apply ASTM A36 structural tolerances to a PED T24 vessel plate without writing them.
Supplementary Requirements
Charpy details. Temperature, energy, location and orientation.
Hardness. After heat treatment and after simulated PWHT when written.
Product analysis. Add this when the destination file wants finished-plate chemistry, especially Ti, B and V.
Elevated-temperature proof strength. Add this when the calculation uses design temperature.
Simulated PWHT. Almost always relevant on T24 equipment.
NDE. EN 10160 or the named UT class.
Third-party. EN 10204 3.2 when written.
