EN 10028-2 11CrMo9-10 Steel Plate | 11CrMo9-10 2.25Cr-1Mo Vessel Plate

11CrMo9-10 is the second 2.25Cr-1Mo name in EN 10028-2. Buyers search EN 10028-2 11CrMo9-10, 11CrMo9-10 steel plate, 1.7383, 11CrMo9-10 equivalent and 11CrMo9-10 2.25Cr-1Mo vessel plate. Steel number is 1.7383. The sister name is 10CrMo9-10, steel number 1.7380. They sit in the same chromium-molybdenum family. They are not the same line on a mill certificate.

Yield is in the 310 MPa class at ≤16 mm. Tensile is 480–630 MPa. 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 an 11CrMo9-10 drawing. 13CrMo4-5 is 1.25Cr-0.5Mo. Do not ship 10CrMo9-10 and call the two names identical unless the buyer writes both. 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.

Company scope: China steel mill agent SHH STEEL.

This plate sits in pressure vessel steel plates. Cr-Mo comparisons belong on ASME SA387. Quenched-and-tempered Cr-Mo comparisons belong on ASME SA542.

Cast analysis follows EN 10028-2 Table 1. Product analysis follows EN 10028-1 when ordered. Google queries such as 11CrMo9-10 chemical composition and 1.7383 chemistry should be answered from this table, not from a 13CrMo4-5 table.

Cast Analysis and Product Analysis — EN 10028-2 11CrMo9-10 (1.7383)

Chromium at 2.00–2.50% plus molybdenum at 0.90–1.10% is the 2.25Cr-1Mo pair. Carbon on 11CrMo9-10 is allowed a little higher than the tight 0.08–0.14 band used on 10CrMo9-10. That is one reason the two names stay separate on a purchase order. This is not P91 and not carbon plate. SHH STEEL reports cast analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search 11CrMo9-10 mechanical properties, 11CrMo9-10 yield strength and 1.7383 tensile. Room-temperature values fall with thickness.

Tensile and Yield — EN 10028-2 11CrMo9-10

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Do not quote 310 MPa yield on a 80 mm plate.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.

Search habits mix 11CrMo9-10 equivalent, 1.7383 equivalent and 11CrMo9-10 vs 10CrMo9-10. Those names help a buyer find the right page. They do not authorize substitution.

Buyers pick 11CrMo9-10 when the PED file names this steel name, not 10CrMo9-10 and not Grade 12. Search phrases such as 11CrMo9-10 boiler plate, 1.7383 steel plate and 11CrMo9-10 pressure vessel plate all point here.

Do not ship SA387 Grade 12 Class 2 against 11CrMo9-10. That grade is 1.25Cr-0.5Mo. Do not ship SA387 Grade 91 Class 2. 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.

11CrMo9-10 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.

Usual delivery from SHH STEEL is normalized and tempered EN 10028-2 11CrMo9-10 (+NT). Buyers who search 11CrMo9-10 NT or 11CrMo9-10 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 11CrMo9-10; 1.7383; 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.

Usual supply range from SHH STEEL for 11CrMo9-10 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.

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.

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.
