GB/T 713 07Cr2AlMoR Steel Plate | 07Cr2AlMoR Vessel Plate

GB/T 713 07Cr2AlMoR, also written GB/T 713.2 07Cr2AlMoR, 07Cr2AlMoRE and 07Cr2AlMoR steel plate, is a Chinese low-carbon Cr-Al-Mo 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 0.07% C, 2% Cr, Al, Mo, and R for vessel. Yield is 260 MPa at 6–36 mm. Tensile is 420–580 MPa. Delivery is normalizing plus tempering. Tempering shall not be lower than 680 °C. Impact is commonly 20 °C, 47 J. Rare earth may be added when the buyer writes it. 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 “CrAlMo vessel plate” is incomplete. Write GB/T 713 07Cr2AlMoR. Do not ship 12Cr2Mo1R against a 07Cr2AlMoR drawing. Do not ship 15CrMoR against a 07Cr2AlMoR drawing. Do not ship Q345R against a 07Cr2AlMoR drawing. Aluminum is required here. Carbon is kept very low. Molybdenum is 0.30–0.50%, not the 0.90–1.10% band used on 12Cr2Mo1R.

07Cr2AlMoR was added in GB/T 713-2014 together with Q420R and 12Cr2Mo1VR. It is used on spherical tanks and petrochemical vessels that want a low-carbon 2% Cr plate with aluminum, not a classic 2.25Cr-1Mo plate.

This page is not carbon Q245R / Q345R. It is not Mn-Mo-Nb 18MnMoNbR. It is not 2.25Cr-1Mo 12Cr2Mo1R. 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. ASME comparisons belong on ASME SA387, not as automatic substitutes. There is no exact SA-387 twin for the Al addition.

GB/T 713 07Cr2AlMoR 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 07Cr2AlMoR

Carbon is kept at 0.09% max. Aluminum is required at 0.30–0.50%. That package is the difference versus 12Cr2Mo1R. GB/T 713.2 also allows an appropriate amount of rare earth when the buyer writes it. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Yield starts at 260 MPa at 6–36 mm and falls as thickness rises.

Tensile and Yield — GB/T 713 07Cr2AlMoR

Elongation is commonly 21% min. Impact is 20 °C, 47 J. Elevated-temperature proof stress is published for 200–300 °C.

Elevated-temperature yield (typical published minima, MPa, >20–60 mm)

Do not quote 260 MPa yield on a 50 mm plate. Do not treat 420–580 MPa tensile as permission to stamp SA387 Gr.22 Cl.2 or SA387 Gr.12 Cl.2. Those books do not use this band.

These names are project-comparison grades. They are not automatic substitutes. Dual marking is uncommon on 07Cr2AlMoR because the aluminum addition is not a standard SA-387 requirement.

ASME SA515 and ASME SA203 are not 07Cr2AlMoR.

GB/T 713 07Cr2AlMoR is selected for spherical tanks, petrochemical shells and other pressure equipment that name the Chinese low-carbon Cr-Al-Mo vessel book. Aluminum and 2% chromium are the reason this grade exists. It is not a substitute for 12Cr2Mo1R hydrogen-service 2.25Cr-1Mo plate unless the drawing says so.

It is not automatically an ASME Section VIII plate. If the vessel is ASME, the drawing should name an ASME or ASTM grade. Do not assume SA387 Gr.22 Cl.2 covers the Al addition.

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. Stainless inquiries belong on ASME SA240 or ASTM A240.

07Cr2AlMoR is killed low-carbon Cr-Al-Mo 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 low-carbon Cr-Al-Mo content, not a 12Cr2Mo1R 2.25Cr-1Mo 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 07Cr2AlMoR. 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 07Cr2AlMoR; heat number; heat analysis; product analysis when ordered; Alt; rare earth when added; 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.

Usual supply range from SHH STEEL for 07Cr2AlMoR vessel plate:

• Thickness: commonly 6 mm – 60 mm. Confirm any request above 60 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 07Cr2AlMoR 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.

Rare earth. Write it if 07Cr2AlMoRE marking is required.

Elevated-temperature proof stress. 200–300 °C or the design temperature.

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.
