GB/T 713 12Cr2Mo1R Steel Plate | 12Cr2Mo1R Cr-Mo Vessel Plate

GB/T 713 12Cr2Mo1R, also written GB/T 713.2 12Cr2Mo1R and 12Cr2Mo1R steel plate, is a Chinese 2.25Cr-1Mo boiler and pressure-vessel plate. Current product rules sit in GB/T 713.2-2023. Buyers still search GB/T 713. The name itself is the search term: about 0.12% C, 2% Cr, 1% Mo, and R for vessel. Yield is 310 MPa in the usual thickness band. Tensile is 520–680 MPa. Delivery is normalizing plus tempering. Tempering shall not be lower than 680 °C. Impact is commonly 20 °C, 47 J. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) for this grade.

A purchase order that only says “2.25Cr-1Mo vessel plate” is incomplete. Write GB/T 713 12Cr2Mo1R. Do not ship 15CrMoR against a 12Cr2Mo1R drawing. Do not ship 14Cr1MoR against a 12Cr2Mo1R drawing. Do not ship 12Cr1MoVR against a 12Cr2Mo1R drawing. Do not ship SA387 Gr.22 Cl.2 and stamp 12Cr2Mo1R because tensile looks close. Dual marking is possible only when both books are fully met.

12Cr2Mo1R is the Chinese sister of ASME SA-387 Grade 22. It is the plate named when the Chinese vessel book still applies and the alloy is 2.25Cr-1Mo, not 1.25Cr-0.5Mo.

This page is not carbon Q245R / Q345R. It is not Mn-Mo-Nb 18MnMoNbR. It is not 1.25Cr-0.5Mo 15CrMoR or 14Cr1MoR. It is not QT alloy under ASME SA543.

Company scope: global steel mill sourcing partner – SHH STEEL.

This plate sits in pressure vessel steel plates and ASME SA387 comparison work. ASME comparisons belong on ASME SA387 Grade 22, not as automatic substitutes.

GB/T 713 12Cr2Mo1R heat analysis follows GB/T 713.2 Table 1. Product analysis follows the permitted deviations in GB/T 713.1. Write “heat + product analysis” on the order if both are required.

Heat Analysis and Product Analysis — GB/T 713 12Cr2Mo1R

Chromium near 2.25% and molybdenum near 1.00% are required. That is the difference versus 15CrMoR and 14Cr1MoR. Do not treat 12Cr1MoVR chemistry as 12Cr2Mo1R. Vanadium is the extra addition on 12Cr1MoVR / 12Cr2Mo1VR, not on this grade. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Yield starts at 310 MPa in the usual thickness band.

Tensile and Yield — GB/T 713 12Cr2Mo1R

Elongation is commonly 19% min. Impact is 20 °C, 47 J. Elevated-temperature proof stress is published for this grade. Write the design temperature on the order if the vessel file needs those values.

Do not treat 520–680 MPa tensile as permission to stamp SA387 Gr.22 Cl.1 or SA387 Gr.22 Cl.2 without checking Class, yield, impact and PWHT. Class 1 and Class 2 are not the same ASME delivery.

These names are project-comparison grades. They are not automatic substitutes.

ASME SA515 and ASME SA203 are not 12Cr2Mo1R.

GB/T 713 12Cr2Mo1R is selected for boilers, hydrotreaters, heat exchangers and other pressure equipment that name the Chinese 2.25Cr-1Mo vessel book. Chromium near 2.25% and molybdenum near 1% support elevated-temperature strength and hydrogen service when the extras are written. It is not automatically an ASME Section VIII plate. If the vessel is ASME, the drawing should name SA387 Gr.22 Cl.2 or SA387 Gr.22 Cl.1.

SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia. It is not nickel low-temp plate like SA203 Gr.D. It is not QT Ni-Cr-Mo like SA543 Type B Cl.1. It is not 1.25Cr-0.5Mo like SA387 Gr.12 Cl.2. Stainless inquiries belong on ASME SA240 or ASTM A240.

12Cr2Mo1R is killed 2.25Cr-1Mo vessel plate. Welding is production welding, and Code welding when the equipment is a vessel.

Qualify procedures to the applicable code. For ASME work that happens to use a dual-named plate, use ASME Section IX. Consumables should match the 2.25Cr-1Mo content, not a 15CrMoR / SA387 Gr.12 Cl.2 procedure and not a plain Q345R procedure. Preheat 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 GB/T 713 12Cr2Mo1R. Tempering shall not be lower than 680 °C. As-rolled shipment is not the default.

If the vessel will see PWHT, test coupons shall follow a simulated cycle when the order names it. This is not the 650 °C temper route used on 15CrMoR / 14Cr1MoR. Special heat treatment, extra simulation or third-party hold points add time. Plan about two months when those extras are on the order.

The certificate lists GB/T 713 12Cr2Mo1R; heat number; heat analysis; product analysis when ordered; tensile results to the correct thickness column; N+T and tempering temperature; impact at 20 °C or the named temperature; elevated-temperature proof stress when ordered. Certificates may be EN 10204 3.1 or EN 10204 3.2. Dual marking to SA387 Gr.22 Cl.2 is available only when both books are met.

Usual supply range from SHH STEEL for 12Cr2Mo1R Cr-Mo vessel plate:

• Thickness: commonly 6 mm – 200 mm. Confirm any request above 150 mm against mill capability
• Width: 1500 mm – 4000 mm
• Length: 3000 mm – 12000 mm
• Cut-to-length plates and nest sizes inside those limits

Ship plate inquiries belong on shipbuilding steel plates or BV Rules. Weathering plate belongs on EN 10025-5 or Corten A/B. TMCP fine-grain structural belongs on EN 10025-4. QT structural belongs on EN 10025-6. Ordinary structural belongs on EN 10025-2 or JIS G3106.

Dimensional limits follow GB/T 713.1 and the mill rolling standard named on the order. Do not apply ASTM A36/A36M structural tolerances to a Chinese vessel plate without writing them. UT to GB/T 2970, JB/T 4730, EN 10160 or ASTM A435 / A577 / A578 is added when the order names it.

Most export GB/T 713 12Cr2Mo1R orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. GB default is commonly 20 °C / 47 J.

Product analysis. Add this when the destination file wants finished-plate chemistry.

Elevated-temperature proof stress. Design temperature as written.

Simulated PWHT. When the equipment will be stress-relieved.

NDE. UT per the named method.

Z-direction. Z15 / Z25 / Z35 when the drawing names it.

HIC / NACE / SSC / hydrogen service. Only when written.

Third-party. EN 10204 3.2, with inspectors arranged for US, Mexican, European, Middle East, Japanese or Korean documentation packages.

Stainless inquiries belong on stainless steel products, JIS G4305 or AISI stainless. Other vessel comparisons: SA203 Gr.B, SA302 Gr.B, A516 Grade 70, SA533 Type C Cl.1, SA517 Gr.P, SA738 Gr.C.
