GB/T 713.4 06Ni9DR Steel Plate | 06Ni9DR 9Ni -196°C Vessel Plate

06Ni9DR is the naming example in GB/T 713.4-2023. The standard writes it out: 06 = average carbon in parts per ten thousand, Ni9 = about 9% nickel, DR = low-temperature vessel. Buyers search GB/T 713.4 06Ni9DR, 06Ni9DR 9Ni -196°C vessel plate, 9Ni steel, GB/T 24510 06Ni9DR and GB/T 3531 06Ni9DR. All of those names belong on this page.

Current product rules sit in GB/T 713.4-2023. That book replaces GB/T 24510-2017. The same commercial name also left GB/T 3531-2014 when nickel cryogenic grades moved into Part 4. Do not look for 06Ni9DR in GB/T 713.3. That part stops at low-alloy grades such as 09MnNiDR.

Yield is 560 MPa at 5–30 mm. Tensile is 680–820 MPa. Delivery is quenched and tempered or double-quenched and tempered. Impact is −196 °C. Lateral expansion shall not be less than 0.64 mm. Residual magnetism shall not exceed 50 gauss. After heat treatment the plate is shot-blasted. SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin) for this grade.

Do not ship 08Ni3DR against 06Ni9DR. 08Ni3DR is 3.5Ni and −100 °C. Do not ship 09MnNiDR. That grade is 0.3–0.8% Ni in GB/T 713.3. Do not ship 07Ni5DR or 06Ni7DR and call them 9Ni.

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

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

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 06Ni9DR

Nickel is the grade. 8.50–10.00% is not 3.5Ni and not 0.8Ni. Carbon and sulfur stay low because the plate has to hold −196 °C. SHH STEEL reports heat analysis on every certificate and product analysis when the order names it.

Density of 9Ni plate is about 7.89 g/cm³, not the 7.85 g/cm³ used on carbon vessel plate. Use 7.89 g/cm³ for weight.

Tensile and Yield — GB/T 713.4 06Ni9DR

Elongation is 18% min. Impact is −196 °C. Lateral expansion shall not be less than 0.64 mm. Delivery is QT or Q+Q+T. Plates not greater than 12 mm may be delivered double-normalized and tempered when the mill and the order agree.

Do not quote 560 MPa yield on a 60 mm plate. Do not treat 680–820 MPa tensile as permission to stamp SA203 Gr.D. SA-203 Grade D is 3.5Ni.

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

Buyers pick 06Ni9DR for LNG tanks, liquid-nitrogen equipment and other −196 °C vessels that name the Chinese 9Ni book. It is the only ferritic vessel grade in this family intended for that temperature. 3.5Ni, 5Ni and 7Ni do not replace it.

It is not an ASME Section VIII plate by default. An ASME 9Ni file should name SA353 or SA553 and then write the extras. Dual marking is possible only when chemistry, QT, tensile, −196 °C impact, lateral expansion and residual magnetism fit both books.

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.

06Ni9DR is 9Ni cryogenic plate in the quenched-and-tempered condition. Welding is Code welding on LNG work.

Qualify to the applicable code. ASME dual-name work uses ASME Section IX. Consumables must be a 9Ni procedure, not a 3.5Ni SA203 Gr.D procedure and not a 09MnNiDR procedure. Heat-affected-zone toughness at −196 °C is the item that fails first if the WPS is wrong. Preheat, interpass and PWHT follow the 9Ni procedure, not a carbon-vessel habit. The fabricator owns the WPS. SHH STEEL can share mill heat data for that review.

Usual delivery from SHH STEEL is quenched-and-tempered or double-quenched-and-tempered GB/T 713.4 06Ni9DR. GB/T 713.4 requires QT or Q+Q+T for this grade. After heat treatment the plate is shot-blasted. Residual magnetism is checked and shall not exceed 50 gauss.

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. 9Ni QT is not a 16MnDR stock item.

The certificate lists GB/T 713.4 06Ni9DR; heat number; heat analysis; product analysis when ordered; tensile to the correct thickness column; QT or Q+Q+T; impact at −196 °C; 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.

Usual supply range from SHH STEEL for 06Ni9DR 9Ni -196°C vessel plate:

• Thickness: commonly 5 mm – 80 mm. GB/T 713.4 allows nickel plates up to 150 mm; confirm 9Ni capability above 80 mm
• Width: 1500 mm – 3500 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 9Ni vessel plate without writing them. UT to NB/T 47013.3 Class I is the GB default. EN 10160 or ASTM A578 may be added when the order names it.

Most export 06Ni9DR orders add extras. SHH STEEL does not assume them.

Charpy details. −196 °C, 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.

Z-direction. Only when written. 9Ni tanks usually care more about −196 °C toughness than Z35.

Third-party. EN 10204 3.2, with inspectors arranged for US, Mexican, European, Middle East, Japanese or Korean LNG 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.

SHH STEEL is a global steel mill sourcing partner and steel manufacturer & exporter (mill-direct, China origin). We supply ASTM / ASME / EN / DIN / JIS / GB steel to the USA, Mexico, South America, Europe, the Middle East, Africa and Asia. On GB/T 713.4 06Ni9DR that means mill pricing, 06Ni9DR chemistry reported as heat analysis and as product analysis when ordered, recorded QT or Q+Q+T, tensile results to the correct thickness column, −196 °C impact with lateral expansion, residual magnetism, shot blast, 3.1 as standard and 3.2 when specified.

We keep the grade on the order. 06Ni9DR is not 08Ni3DR. 06Ni9DR is not 07Ni5DR. 06Ni9DR is not 06Ni7DR. 06Ni9DR is not 09MnNiDR. 06Ni9DR is not SA203 Gr.D. If the drawing says 3.5添加行Ni, we will not ship 9Ni and call nickel close. If the drawing says SA353, we will only dual-mark when both books are met.
