GB/T 713 13MnNiMoR Steel Plate | 13MnNiMoR Vessel Plate

GB/T 713 13MnNiMoR, also written GB/T 713.2 13MnNiMoR and 13MnNiMoR steel plate, is a Chinese Mn-Ni-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 0.13% C, Mn, Ni, Mo, and R for vessel. Yield is 390 MPa at 30–100 mm. Tensile is 570–720 MPa. Delivery is normalizing plus tempering. Tempering shall not be lower than 620 °C. Impact is commonly 0 °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 “MnNiMo vessel plate” is incomplete. Write GB/T 713 13MnNiMoR. Do not ship Q345R or Q370R against a 13MnNiMoR drawing. Do not ship 18MnMoNbR against a 13MnNiMoR drawing. Do not ship SA302 Gr.C and stamp 13MnNiMoR because both contain nickel and molybdenum.

This page is not Q245R / Q345R carbon vessel plate. It is not Cr-Mo 15CrMoR. It is not QT alloy under ASME SA387. It is not low-temperature 16MnDR under GB/T 713.3.

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

This plate sits in pressure vessel steel plates. ASME comparisons belong on ASME SA302 and ASME SA533, not as automatic substitutes.

GB/T 713 13MnNiMoR 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 13MnNiMoR

Nickel, chromium and molybdenum are required. That is the difference versus 18MnMoNbR, which uses niobium instead of nickel. Do not treat 18MnMoNbR chemistry as 13MnNiMoR. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Yield starts at 390 MPa at 30–100 mm and falls as thickness rises.

Tensile and Yield — GB/T 713 13MnNiMoR

Elongation is commonly 18% min. Impact is 0 °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.

Typical published elevated-temperature yield minima at 30–100 mm: about 355 MPa at 200 °C, 350 MPa at 250 °C, 345 MPa at 300 °C, 335 MPa at 350 °C, 305 MPa at 400 °C. Confirm the exact GB/T 713.2 Table 3 column for the ordered thickness.

Do not treat 570–720 MPa tensile as permission to stamp SA302 Gr.C, SA302 Gr.D or SA533 Type B Cl.1 without checking yield, impact and PWHT.

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

ASME SA515, ASME SA387 Grade 22 and ASME SA203 are not 13MnNiMoR.

GB/T 713 13MnNiMoR is selected for boilers, drums, thick shells and other pressure equipment that name the Chinese Mn-Ni-Mo vessel book. Nickel supports toughness. Molybdenum supports elevated-temperature strength. It is not automatically an ASME Section VIII plate. If the vessel is ASME, the drawing should name an ASME or ASTM grade such as SA302 Gr.C, SA302 Gr.D or SA533 Type B 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 Cr-Mo like SA387 Gr.22 Cl.2. Stainless inquiries belong on ASME SA240 or ASTM A240.

13MnNiMoR is killed Mn-Ni-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 570–720 MPa tensile band and the Ni-Mo content, not a plain Q345R procedure and not a SA387 Gr.22 Cl.2 Cr-Mo procedure. Preheat follows 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 13MnNiMoR. Tempering shall not be lower than 620 °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 carbon normalize route used on Q345R and not the Cr-Mo N+T route used on 15CrMoR. 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 13MnNiMoR; heat number; heat analysis; product analysis when ordered; tensile results to the correct thickness column; N+T and tempering temperature; impact at 0 °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 13MnNiMoR vessel plate:

• Thickness: commonly 30 mm – 150 mm. Confirm any request outside that band 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 13MnNiMoR orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. GB default is commonly 0 °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. 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.A, A516 Grade 70, SA533 Type C Cl.2, SA517 Gr.P, SA738 Gr.C.
