EN 10028-2 12CrMoV12-10 Steel Plate | 12CrMoV12-10 3Cr-1Mo-V Vessel Plate

12CrMoV12-10 is the 3Cr-1Mo-V grade in EN 10028-2. Buyers search EN 10028-2 12CrMoV12-10, 12CrMoV12-10 steel plate, 1.7767, 12CrMoV12-10 equivalent and 12CrMoV12-10 3Cr-1Mo-V vessel plate. Steel number is 1.7767. Chromium is about 2.70–3.30%. Molybdenum is about 0.90–1.20%. Vanadium is about 0.25–0.35%. That vanadium is why this page is not 10CrMo9-10 and not 11CrMo9-10.

Yield is in the 400 MPa class at ≤16 mm. Tensile is 580–760 MPa. Delivery is usually normalized and tempered (+NT). Some mill routes use quench and temper when thickness or the order requires it. 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 10CrMo9-10 against a 12CrMoV12-10 drawing. 10CrMo9-10 is 2.25Cr-1Mo without this vanadium band. Do not ship 13CrMo4-5 and call 1.25Cr close to 3Cr. The closest ASME talk grades are SA387 Grade 21 Class 2 and SA832 Grade 21V. SA387 Grade 21 Class 1 is the lower class in that 3Cr family. Dual marking is possible only when chemistry, tensile, hardness, impact and delivery all fit.

Company scope: global exporter SHH STEEL.

This plate sits in pressure vessel steel plates. Cr-Mo comparisons belong on ASME SA387. Cr-Mo-V vessel comparisons belong on ASME SA832 and ASME SA542.

Cast analysis follows EN 10028-2 Table 1. Product analysis follows EN 10028-1 when ordered. People who type 12CrMoV12-10 chemical composition or 1.7767 chemistry into Google want chromium near 3%, molybdenum near 1% and vanadium on the same line. A 10CrMo9-10 table does not answer that.

Cast Analysis and Product Analysis — EN 10028-2 12CrMoV12-10 (1.7767)

Vanadium is not an optional extra. It is the letter in the grade name. Chromium at 2.70–3.30% is the 3Cr step above 10CrMo9-10. Molybdenum stays near 1%. This is not P91 9Cr plate and not 1.25Cr-0.5Mo plate. SHH STEEL reports cast analysis on every certificate and product analysis when ordered. Density is 7.85 g/cm³.

Buyers search 12CrMoV12-10 mechanical properties, 12CrMoV12-10 yield strength and 12CrMoV12-10 tensile strength. Room-temperature values fall with thickness. Use the thickness column on the mill certificate.

Tensile and Yield — EN 10028-2 12CrMoV12-10

Elongation is typically 18% min on thinner plate. Impact at 0 °C, 27 J, is the usual option when the order names it. Some files ask hardness after heat treatment because vanadium-bearing Cr-Mo can run hard if tempering is short. Write hardness if the vessel specification uses it. Elevated-temperature proof strength is part of EN 10028-2. Ask for that table when the calculation uses design temperature.

Do not quote 400 MPa yield on an 80 mm plate. Do not treat 580–760 MPa tensile as permission to stamp SA387 Grade 21 Class 2 without checking vanadium, class and PWHT.

People type 12CrMoV12-10 equivalent, 1.7767 equivalent and 12CrMoV12-10 vs SA387 Grade 21 because there is no one-line twin. Give the talk list. Keep the EN name on the order.

Buyers pick 12CrMoV12-10 when the PED file wants 3% chromium, about 1% molybdenum and vanadium together. That combination is used on high-temperature pressure equipment that has already left 2.25Cr-1Mo behind and has not jumped to 9Cr P91. Search phrases such as 12CrMoV12-10 boiler plate, 1.7767 steel plate and 12CrMoV12-10 pressure vessel plate all point here.

Do not ship SA387 Grade 22 Class 2 against 12CrMoV12-10. Grade 22 is 2.25Cr-1Mo. Do not ship SA387 Grade 91 Class 2. That grade is 9Cr-1Mo-V-Nb. An ASME file that wants 3Cr-1Mo should name SA-387 Grade 21 on ASME SA387 and then write class and vanadium 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. The purchase is not limited to China, Hong Kong or Singapore.

12CrMoV12-10 is 3Cr-1Mo-V 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 3Cr-1Mo-V practice. A carbon procedure written for SA516 Grade 70 is not valid. A 2.25Cr-1Mo procedure written for SA387 Grade 22 Class 2 is the previous family, not this one. A P91 procedure written for SA387 Grade 91 Class 2 is the next family. Preheat, interpass, hydrogen control and PWHT window all belong in the WPS. Vanadium-bearing weld metal does not like a copied Grade 22 temper. 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 12CrMoV12-10 (+NT). Quench and temper is used when the mill route and the order require it. Buyers who search 12CrMoV12-10 heat treatment, 12CrMoV12-10 PWHT or 12CrMoV12-10 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 vanadium-bearing plate. 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 12CrMoV12-10; 1.7767; heat number; cast analysis including chromium, molybdenum and vanadium; product analysis when ordered; tensile to the correct thickness column; +NT or QT; hardness when ordered; 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 12CrMoV12-10 3Cr-1Mo-V vessel plate:

• Thickness: commonly 8 mm – 120 mm, thicker by mill agreement
• Width: 1500 mm – 3500 mm
• Length: 3000 mm – 12000 mm

2.25Cr-1Mo plate belongs on 12Cr2Mo1R steel plate. 1Cr-0.5Mo plate belongs on 15CrMoR 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 3Cr-1Mo-V vessel plate without writing them.

Charpy details. Temperature, energy, location and orientation. Do not assume 0 °C.

Hardness. After heat treatment and after simulated PWHT when written.

Product analysis. Add this when the destination file wants finished-plate chemistry, especially V, Cr and Mo.

Elevated-temperature proof strength. Add this when the calculation uses design temperature.

Simulated PWHT. Almost always relevant on this grade.

NDE. EN 10160 or the named UT class.

Third-party. EN 10204 3.2 when written.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). On EN 10028-2 12CrMoV12-10 that means mill pricing from Wuyang, Angang, Baosteel and other first-line mills, 1.7767 chemistry reported as cast analysis and as product analysis when ordered, vanadium shown on the certificate, recorded +NT or QT, tensile results to the correct thickness column, 3.1 as standard and 3.2 when specified.

We keep the grade on the order. 12CrMoV12-10 is not 10CrMo9-10. 12CrMoV12-10 is not SA387 Grade 22 Class 2. 12CrMoV12-10 is not P91. 12CrMoV12-10 is not Q345R steel plate. If the drawing says Grade 22, we will not ship 3Cr-1Mo-V and call chromium close.
