EN 10028-2 10CrMo9-10 Steel Plate | 10CrMo9-10 2.25Cr-1Mo Vessel Plate
What is EN 10028-2 10CrMo9-10 Steel?
10CrMo9-10 is the 2.25Cr-1Mo grade in EN 10028-2. Buyers search EN 10028-2 10CrMo9-10, 10CrMo9-10 steel plate, 1.7380, 10CrMo9-10 equivalent and 10CrMo9-10 2.25Cr-1Mo vessel plate. The numbers mean about 2.25% chromium and 1.0% molybdenum. This page is not 13CrMo4-5 and not P355GH.
Yield is 310 MPa at ≤16 mm. Tensile is 480–630 MPa. Steel number is 1.7380. Delivery is usually normalized and tempered (+NT). SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) for this grade.
Do not ship 13CrMo4-5 against a 10CrMo9-10 drawing. 13CrMo4-5 is 1.25Cr-0.5Mo. The closest ASME comparison is SA387 Grade 22 Class 1 or SA387 Grade 22 Class 2. The closest Chinese comparison is 12Cr2Mo1R steel plate. Dual marking is possible only when chemistry, tensile, impact and delivery all fit.

Chemical Composition
Cast analysis follows EN 10028-2 Table 1. Product analysis follows EN 10028-1 when ordered. Google queries such as 10CrMo9-10 chemical composition and 1.7380 chemistry should be answered from this table.
Cast Analysis and Product Analysis — EN 10028-2 10CrMo9-10 (1.7380)
| Element | Cast Analysis (%) | Product Analysis, when ordered (%) |
|---|---|---|
| Carbon (C) | 0.08 – 0.14 | 0.06 – 0.16 |
| Silicon (Si), max | 0.50 | 0.55 |
| Manganese (Mn) | 0.40 – 1.00 | 0.35 – 1.08 |
| Phosphorus (P), max | 0.025 | 0.030 |
| Sulfur (S), max | 0.010 | 0.013 |
| Nitrogen (N), max | 0.012 | 0.014 |
| Chromium (Cr) | 2.00 – 2.50 | 1.90 – 2.60 |
| Copper (Cu), max | 0.30 | 0.35 |
| Molybdenum (Mo) | 0.90 – 1.10 | 0.85 – 1.15 |
| Nickel (Ni), max | 0.30 | 0.35 |
| Vanadium (V), max | 0.20 | 0.22 |
Chromium at 2.00–2.50% plus molybdenum at 0.90–1.10% is the pair that makes 10CrMo9-10 different from 13CrMo4-5. It is not P91 9Cr plate and not carbon plate. SHH STEEL reports cast analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.
Mechanical Properties
Buyers search 10CrMo9-10 mechanical properties, 10CrMo9-10 yield strength and 1.7380 tensile. Room-temperature values fall with thickness.
Tensile and Yield — EN 10028-2 10CrMo9-10
| Thickness (mm) | Yield min (MPa) | Tensile (MPa) |
|---|---|---|
| ≤ 16 | 310 | 480 – 630 |
| 16 – 40 | 300 | 480 – 630 |
| 40 – 60 | 290 | 470 – 620 |
| 60 – 100 | 270 | 460 – 610 |
| Density | 7.85 g/cm³ | 7.85 g/cm³ |
Elongation is typically 18–20% min on thinner plate. Impact at 0 °C, 27 J, is the usual option when the order names it. Elevated-temperature proof strength is part of EN 10028-2. Ask for that table when the vessel calculation uses design temperature.
Do not quote 310 MPa yield on a 80 mm plate. Do not treat 480–630 MPa tensile as permission to stamp SA387 Grade 22 Class 2 without checking class, PWHT and impact.

Equivalent Material Grades
Search habits mix 10CrMo9-10 equivalent, 1.7380 equivalent and 10CrMo9-10 vs SA387 Grade 22. Those names help a buyer find the right page. They do not authorize substitution.

2.25Cr-1Mo Pressure-Vessel Service
Buyers pick 10CrMo9-10 for PED boilers, hydroprocessing-adjacent shells, heat-exchanger channels and high-temperature vessels that need 2.25Cr-1Mo. Search phrases such as 10CrMo9-10 boiler plate, 1.7380 steel plate and 10CrMo9-10 pressure vessel plate all point to this grade.
Do not ship SA387 Grade 12 Class 2 against 10CrMo9-10. That grade is 1.25Cr-0.5Mo. Do not ship SA387 Grade 91 Class 2 either. That grade is 9Cr. An ASME file that wants 2.25Cr-1Mo should name SA-387 Grade 22 on ASME SA387 and then write class and extras. Dual marking is possible only when both books are met.
SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia.
Weldability
10CrMo9-10 is 2.25Cr-1Mo vessel plate. 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 match 2.25Cr-1Mo practice. A carbon procedure written for SA516 Grade 70 is not valid. A 1.25Cr-0.5Mo procedure written for 13CrMo4-5 is the previous family. Preheat, interpass and PWHT follow thickness and hydrogen control. 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 10CrMo9-10 (+NT). Buyers who search 10CrMo9-10 NT or 10CrMo9-10 heat treatment are asking for this route.
If the vessel will see PWHT, say so. Test coupons then follow a simulated cycle. 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 10CrMo9-10; 1.7380; heat number; cast analysis; product analysis when ordered; tensile to the correct thickness column; +NT; 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 10CrMo9-10 2.25Cr-1Mo vessel plate:
- Thickness: commonly 6 mm – 150 mm, thicker by mill agreement
- Width: 1500 mm – 4000 mm
- Length: 3000 mm – 12000 mm
Vanadium-bearing Cr-Mo belongs on 12Cr1MoVR steel plate or 12Cr2Mo1VR 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 vessel plate without writing them.
Supplementary Requirements
Charpy details. Temperature, energy, location and orientation. 0 °C / 27 J is common, not assumed.
Product analysis. Add this when the destination file wants finished-plate chemistry.
Elevated-temperature proof strength. Add this when the calculation uses design temperature.
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.
