GB/T 713.4 06Ni7DR Steel Plate | 06Ni7DR 7Ni Low Temp Vessel Plate
What is GB/T 713.4 06Ni7DR Steel?
06Ni7DR is the grade GB/T 713.4-2023 added when it replaced GB/T 24510-2017. The old 24510 book had 1.5Ni and did not carry this 7Ni name. The letters mean 06 = average carbon, Ni7 = about 7% nickel, DR = low-temperature vessel. Buyers search GB/T 713.4 06Ni7DR, 06Ni7DR 7Ni low temp vessel plate and 7Ni steel.
Yield is 550 MPa in the mid-thickness band and 540 MPa above that. Tensile is 680–820 MPa. Delivery is quenched and tempered or double-quenched and tempered. Impact specimens shall also meet lateral expansion not less than 0.64 mm. Residual magnetism shall not exceed 50 gauss. After heat treatment the plate is shot-blasted. Those last three rules sit with 06Ni9DR steel plate, not with 08Ni3DR steel plate. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) for this grade.
Do not ship 08Ni3DR steel plate against 06Ni7DR. 08Ni3DR is 3.5Ni. Do not ship 07Ni5DR steel plate and call 5Ni the same as 7Ni. Do not ship 06Ni9DR steel plate and call 9Ni close. Do not ship GB/T 713.3 09MnNiDR steel plate, 16MnDR steel plate, 13MnNiDR steel plate, 15MnNiNbDR steel plate, 11MnNiMoDR steel plate, Q420DR steel plate or Q460DR steel plate. Those grades are low-alloy low-temperature plates, not 7Ni plate.
Do not ship GB/T 713.2 vessel plate against this page either. Q345R steel plate, Q245R steel plate, Q370R steel plate, Q420R steel plate, Q460R steel plate, 15CrMoR steel plate, 14Cr1MoR steel plate, 12Cr2Mo1R steel plate, 12Cr1MoVR steel plate, 12Cr2Mo1VR steel plate, 13MnNiMoR steel plate, 18MnMoNbR steel plate and 07Cr2AlMoR steel plate belong to a different part of GB/T 713.
If the inquiry is Japanese vessel plate, look at SPV235 steel plate, SPV315 steel plate, SPV355 steel plate, SPV410 steel plate or SPV450 steel plate. If the inquiry is German fine-grain plate, look at StE355 steel plate, WStE355 steel plate, TStE355 steel plate or EStE355 steel plate. None of those names replace 06Ni7DR.

Heat analysis follows GB/T 713.4 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 713.4 06Ni7DR
| Element | Heat Analysis (%) | Product Analysis, when ordered (%) |
|---|---|---|
| Carbon (C), max | 0.08 | 0.10 |

Nickel is about 7%. That is not 3.5Ni and not 9Ni. GB/T 713.4 treats 06Ni7DR separately from the Cr+Mo+Cu ≤0.50% note used on the other nickel grades. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it. Density is about 7.87 g/cm³. Use the mill certificate weight if the tank calculation is tight.
Mechanical Properties
Tensile and Yield — GB/T 713.4 06Ni7DR

7Ni Pressure-Vessel Service
Buyers pick 06Ni7DR when the file wants more nickel than 5Ni and does not want to jump to 9Ni LNG inner-tank plate. Strength sits with the 680–820 MPa family used on 06Ni9DR. Extra mill rules also sit with 9Ni: lateral expansion, residual magnetism and shot blast.
It is not an ASME Section VIII plate by default. An ASME file should name SA203 Gr.D, SA353 or SA553 only when that is the actual book. Dual marking is possible only when both books are met.
SHH STEEL supplies this plate to fabricators in the United States, Mexico, South America, Europe, the Middle East, Africa and Asia. Stainless inquiries belong on ASME SA240 or ASTM A240.
Weldability
06Ni7DR is 7Ni plate in the quenched-and-tempered condition. Qualify to the applicable code. ASME dual-name work uses ASME Section IX. Consumables must match 7Ni practice, not a 3.5Ni SA203 Gr.D procedure and not a 9Ni 06Ni9DR procedure copied without review. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.
Heat Treatment and Delivery Condition
Usual delivery from SHH STEEL is quenched-and-tempered or double-quenched-and-tempered GB/T 713.4 06Ni7DR. After heat treatment the plate is shot-blasted. Residual magnetism is checked and shall not exceed 50 gauss. Batches are made by heat-treatment piece, not by a 30 t melt lot used on 08Ni3DR.
If the vessel will see PWHT, say so. Test coupons then follow a simulated cycle. Plan about two months when 3.2 or extra NDE is on the order.
The certificate lists GB/T 713.4 06Ni7DR; heat number; heat analysis; product analysis when ordered; tensile to the correct thickness column; QT or Q+Q+T; impact; lateral expansion; residual magnetism. Certificates may be EN 10204 3.1 or EN 10204 3.2. UT to NB/T 47013.3 Class I is the GB default.
Dimensions
Usual supply range from SHH STEEL for 06Ni7DR 7Ni low temp vessel plate:
- Thickness: commonly 5 mm – 80 mm
- Width: 1500 mm – 3500 mm
- Length: 3000 mm – 12000 mm
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.
Tolerances
Dimensional limits follow GB/T 713.1. Do not apply ASTM A36/A36M structural tolerances without writing them. UT to NB/T 47013.3 Class I is the GB default.
Supplementary Requirements
Charpy details. Temperature, energy, location, orientation and lateral expansion ≥0.64 mm.
Residual magnetism. GB default is not more than 50 gauss.
Shot blast. Required after heat treatment.
Product analysis. Add this when the destination file wants finished-plate chemistry.
Simulated PWHT. When the equipment will be stress-relieved.
NDE. UT Class I unless a tighter class is written.
Third-party. EN 10204 3.2 when written.
