GB/T 3531 06Ni9DR steel plate, also written as 06Ni9DR pressure vessel steel plate, GB3531 06Ni9DR, 06Ni9DR 9%Ni steel plate, GB/T 713.4 06Ni9DR, 9Ni DR plate, is a ~9% nickel cryogenic pressure vessel plate under GB/T 3531 (moved to GB/T 713.4 in the 2023 succession), with typical Charpy at -196°C and high yield about 560 MPa. Gangsteel (HENAN GANG IRON AND STEEL) produces and exports 06Ni9DR / 9% Ni plates for LNG and -196°C cryogenic vessels with MTC.
Data source: Per GB/T 3531-2014 (Steel plates for low temperature pressure vessels; buyers still search “GB/T 3531” / “GB3531”). The 2023 succession splits low-temp coverage into GB/T 713.3 (low-alloy low-temp) and GB/T 713.4 (nickel alloy low-temp). Official mill/certificate grade is 06Ni9DR. Verify the contracted edition and purchase-order supplements before ordering.

GB/T 3531-2014 typical bands. Cryogenic impact and heat treatment must be explicit on the PO/MTC.
Quenched + tempered (or double normalized + tempered per agreement). UT and cryogenic impact are critical PO items.
Typical 5–50 mm under GB/T 3531 tables; confirm mill range.
LNG tanks, ethane/ethylene cryogenic vessels and other -196°C service; often compared with ASTM A353 / A553 Type I / EN 10028-4 X8Ni9 class plates.

Equivalents are engineering references only. Dual certification requires the stricter combined limits on the PO and MTC.
It is a 9% Ni low-temperature pressure vessel steel under GB/T 3531 (Steel plates for low temperature pressure vessels). a ~9% nickel cryogenic pressure vessel plate under GB/T 3531 (moved to GB/T 713.4 in the 2023 succession), with typical Charpy at -196°C and high yield about 560 MPa. Gangsteel lists the official mill/certificate grade as 06Ni9DR. See the full GB/T 3531 06Ni9DR page for chemistry and mechanical tables.
Minimum yield is about 560 MPa across the usual 5–50 mm supply band. Typical tensile bands are shown in the mechanical properties table on this page; confirm the contracted GB/T 3531 or GB/T 713.3/713.4 edition before design.
Charpy KV2 is typically -196°C / ≥100 J. Always state the required Charpy temperature and energy on the purchase order.
Quenched + tempered (or double normalized + tempered per agreement). UT and cryogenic impact are critical PO items.
All sit in the GB/T 3531 low-temperature vessel family (commercial buyers still search GB3531). Sister grades: 16MnDR / 15MnNiDR / 15MnNiNbDR / 09MnNiDR / 08Ni3DR. Hub: GB/T 3531 Steel Plate. Ambient/elevated GB carbon/alloy grades are under GB/T 713 / GB/T 713.2.
Approximate cryogenic counterparts: ASTM A353 / ASME SA353 (A353 plate), ASTM A553 Type I, and EN 10028-4 9% Ni grades. Chemistry, heat treatment and -196°C impact rules differ — dual certification needs the stricter combined limits.
EN 10204 3.1 as standard; 3.2 with third-party inspection when ordered. MTC lists heat analysis, mechanical tests, delivery condition and any optional UT / Z / cryogenic impact results.
