GB/T 713.3 16MnDR Steel Plate | 16MnDR -40°C Vessel Plate

GB/T 713.3 16MnDR, also written 16MnDR steel plate, GB/T 3531 16MnDR and 16MnDR -40°C vessel plate, is a Chinese low-temperature low-alloy 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 16MnDR. The name itself is the search term: about 0.16% C, Mn, and DR for low-temperature vessel. Yield is 315 MPa at 5–16 mm. Tensile is 490–620 MPa. Delivery is normalizing or normalizing plus tempering. Impact is −40 °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 “low-temp vessel plate” is incomplete. Write GB/T 713.3 16MnDR. Do not ship Q345R against a 16MnDR drawing. Do not ship 09MnNiDR against a 16MnDR drawing. Q345R is the room-temperature sister under GB/T 713.2. 09MnNiDR is the −70 °C nickel grade in the same GB/T 713.3 book. They are not interchangeable.

This page is not 15MnNiNbDR. It is not Q420DR / Q460DR. It is not 08Ni3DR or 06Ni9DR; those nickel cryogenic grades now sit in GB/T 713.4-2023. It is not QT high-strength plate under GB/T 713.6.

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

This plate sits in pressure vessel steel plates. ASME comparisons belong on ASME SA516 and ASME SA662, not as automatic substitutes.

GB/T 713.3 16MnDR 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 16MnDR

Aluminum is required unless Nb+V+Ti ≥0.015% and the mill uses that route. Phosphorus and sulfur are tighter than ordinary Q345R. That is one reason 16MnDR is not a stamp-over of Q345R. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Yield starts at 315 MPa at 5–16 mm and falls as thickness rises. GB/T 713.3 lowered the minimum thickness of 16MnDR from 6 mm to 5 mm.

Tensile and Yield — GB/T 713.3 16MnDR

Elongation is commonly 21% min. Impact is −40 °C, 47 J. Do not quote −70 °C impact on 16MnDR unless the order names a tighter extra. −70 °C belongs on 09MnNiDR.

Do not treat 490–620 MPa tensile as permission to stamp SA516 Gr.70 or SA662 Gr.C without checking impact temperature, energy and PWHT.

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

ASME SA515 and ASME SA203 are not 16MnDR.

−40 °C Pressure-Vessel Service

GB/T 713.3 16MnDR is selected for LPG tanks, cold-region vessels, separators and other pressure equipment that name the Chinese −40 °C low-alloy vessel book. It is the workhorse grade in GB/T 713.3. If the minimum design temperature is −50 °C or −70 °C, the drawing should name 15MnNiNbDR or 09MnNiDR, not 16MnDR.

It is not automatically an ASME Section VIII plate. If the vessel is ASME, the drawing should name SA516 Gr.70 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 nickel cryogenic 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.

16MnDR is killed low-alloy 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 490–620 MPa tensile band and the −40 °C toughness target, not a plain Q345R 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 16MnDR. As-rolled shipment is not the default for this grade.

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 16MnDR; heat number; heat analysis; product analysis when ordered; tensile results to the correct thickness column; N or N+T; impact at −40 °C. Certificates may be EN 10204 3.1 or EN 10204 3.2. Dual marking to SA516 Gr.70 is available only when both books are met.

Usual supply range from SHH STEEL for 16MnDR -40°C vessel plate:

• Thickness: commonly 5 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 16MnDR orders add extras. SHH STEEL does not assume them.

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.
