GB/T 713.3 13MnNiDR Steel Plate | 13MnNiDR Low Temp Vessel Plate

13MnNiDR is not an old GB/T 3531 name that simply changed books. It is one of the four grades added when GB/T 713.3-2023 replaced GB/T 3531-2014. The other three additions are Q420DR, Q460DR and 11MnNiMoDR. If a 2014 drawing never mentioned 13MnNiDR, do not assume the buyer meant 13MnNiMoR. Those are different steels in different parts of GB/T 713.

The current name is GB/T 713.3 13MnNiDR, also written 13MnNiDR steel plate and 13MnNiDR low temp vessel plate. About 0.13% C, Mn, Ni, DR for low-temperature vessel. Yield is 345 MPa at 5–36 mm. Tensile is 490–610 MPa. Delivery is normalized or normalized and tempered. Impact is −60 °C, 60 J. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) for this grade.

Do not ship 16MnDR against 13MnNiDR. 16MnDR is −40 °C. Do not ship 09MnNiDR against 13MnNiDR. 09MnNiDR is −70 °C with lower carbon and lower strength. Do not ship 15MnNiNbDR against 13MnNiDR. That grade is −50 °C with required niobium. Do not ship 13MnNiMoR. 13MnNiMoR is a GB/T 713.2 elevated-temperature Mn-Ni-Mo vessel plate, not a GB/T 713.3 low-temperature plate.

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.

Heat analysis follows GB/T 713.3 Table 1. Product analysis follows GB/T 713.1. Write both on the PO if the destination file needs finished-plate chemistry.

Heat Analysis and Product Analysis — GB/T 713.3 13MnNiDR

Nickel is required. Carbon sits between 16MnDR and 09MnNiDR. Sulfur is tight. Molybdenum is residual, not the 0.20–0.40% band used on 13MnNiMoR. That is the fastest way to stop a mill from rolling the wrong sister grade. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Tensile and Yield — GB/T 713.3 13MnNiDR

Elongation is 22% min. Impact is −60 °C, 60 J. Bend is 180°, D=3a. Delivery is N or N+T.

Do not quote 345 MPa yield on an 80 mm plate. Do not quote −70 °C as the GB default. That temperature belongs on 09MnNiDR and 11MnNiMoDR. Do not treat 490–610 MPa tensile as permission to stamp SA516 Gr.70 or SA203 Gr.A.

Comparison names help a buyer search. They do not authorize substitution.

Buyers pick 13MnNiDR when they want a GB/T 713.3 nickel grade between 16MnDR (−40 °C) and 09MnNiDR (−70 °C), with yield in the 345 MPa band. It is a 2023 addition, so older purchase specs may not list it. Confirm the drawing before rolling.

It is not an ASME Section VIII plate by default. An ASME file should name SA516 Gr.70, SA662 Gr.C or SA203 Gr.A and then write the extras.

SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia. It is not 3.5Ni plate under GB/T 713.4. Stainless inquiries belong on ASME SA240 or ASTM A240.

13MnNiDR is killed Mn-Ni vessel plate. Treat welding as production welding, and as Code welding when the equipment is a vessel.

Qualify to the applicable code. ASME dual-name work uses ASME Section IX. Match consumables to the 490–610 MPa tensile band and the −60 °C toughness target. A 16MnDR procedure is not automatically valid. A 09MnNiDR procedure is not automatically valid. A 13MnNiMoR procedure is the wrong book. 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 13MnNiDR. As-rolled is not the default.

If the vessel will see PWHT, say so. Test coupons then follow a simulated cycle. Extra simulation, 3.2 hold points or special NDE add time. Plan about two months when those extras are on the order.

The certificate lists GB/T 713.3 13MnNiDR; heat number; heat analysis; product analysis when ordered; tensile to the correct thickness column; N or N+T; impact at −60 °C. Certificates may be EN 10204 3.1 or EN 10204 3.2.

Usual supply range from SHH STEEL for 13MnNiDR low temp vessel plate:

• Thickness: commonly 5 mm – 100 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 13MnNiDR orders add extras. SHH STEEL does not assume them.

Charpy details. Temperature, energy, location and orientation. GB default is −60 °C / 60 J.

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

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