GB/T 713.3 09MnNiDR Steel Plate | 09MnNiDR -70°C Vessel Plate

GB/T 713.3 09MnNiDR, also written 09MnNiDR steel plate, GB/T 3531 09MnNiDR and 09MnNiDR -70°C vessel plate, is a Chinese nickel low-temperature pressure-vessel plate. Current product rules sit in GB/T 713.3-2023. That book replaces GB/T 3531-2014. Buyers still search GB/T 3531 and 09MnNiDR. The name itself is the search term: about 0.09% C, Mn, Ni, and DR for low-temperature vessel. Yield is 300 MPa at 6–16 mm. Tensile is 440–570 MPa. Delivery is normalizing or normalizing plus tempering. Impact is −70 °C, 60 J through 80 mm. 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 “-70 °C vessel plate” is incomplete. Write GB/T 713.3 09MnNiDR. Do not ship 16MnDR against a 09MnNiDR drawing. 16MnDR is the −40 °C workhorse in the same book. Do not ship 08Ni3DR against a 09MnNiDR drawing. 08Ni3DR is 3.5Ni and now sits in GB/T 713.4-2023.
This page is not Q345R. It is not 15MnNiNbDR. It is not Q420DR / Q460DR. It is not 06Ni9DR.
Company scope: global steel mill sourcing partner – SHH STEEL.

This plate sits in pressure vessel steel plates. ASME comparisons belong on ASME SA203 and ASME SA662, not as automatic substitutes.

GB/T 713.3 09MnNiDR heat analysis follows GB/T 713.3 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 713.3 09MnNiDR

Nickel is required. Carbon is lower than on 16MnDR. Sulfur is tighter. That package is why 09MnNiDR holds −70 °C and 16MnDR does not. Do not treat 16MnDR chemistry as 09MnNiDR. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Yield starts at 300 MPa at 6–16 mm and falls as thickness rises.

Tensile and Yield — GB/T 713.3 09MnNiDR

Elongation is commonly 23% min. Do not quote −70 °C on a 100 mm plate without checking the 80–120 mm column. That band drops to −60 °C unless the order names a tighter extra.

Do not treat 440–570 MPa tensile as permission to stamp SA203 Gr.A or SA662 Gr.C. SA-203 Grade A is 2.25Ni. 09MnNiDR nickel is only 0.30–0.80%.

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

ASME SA515 is not 09MnNiDR.

GB/T 713.3 09MnNiDR is selected for ethylene-related equipment, cold-region tanks, separators and other pressure equipment that name the Chinese −70 °C Mn-Ni vessel book. Nickel at 0.30–0.80% is the reason this grade holds lower temperature than 16MnDR. It is not 3.5Ni or 9Ni plate. Those grades now sit in GB/T 713.4.

It is not automatically an ASME Section VIII plate. If the vessel is ASME, the drawing should name SA203 Gr.A, SA203 Gr.D or SA662 Gr.C with the impact extras written.

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

09MnNiDR is killed Mn-Ni low-temperature 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 440–570 MPa tensile band and the −70 °C toughness target, not a 16MnDR-only procedure and not a 3.5Ni SA203 Gr.D 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 or normalized-and-tempered GB/T 713.3 09MnNiDR. 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 Cr-Mo 650 °C / 680 °C temper route used on 15CrMoR or 12Cr2Mo1R. 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 713.3 09MnNiDR; heat number; heat analysis; product analysis when ordered; tensile results to the correct thickness column; N or N+T; impact at −70 °C or −60 °C by thickness. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for 09MnNiDR -70°C vessel plate:

• Thickness: commonly 6 mm – 120 mm
• 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 / NB/T 47013.3, EN 10160 or ASTM A435 / A577 / A578 is added when the order names it.

Most export GB/T 713.3 09MnNiDR orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. GB default is −70 °C / 60 J to 80 mm, −60 °C above 80 mm.

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

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.B, A516 Grade 70, SA533 Type C Cl.1, SA517 Gr.P, SA738 Gr.C.
