GB/T 3531 08Ni3DR Steel Plate | 08Ni3DR 3.5%Ni Vessel Plate

GB/T 3531 08Ni3DR steel plate, also written as 08Ni3DR pressure vessel steel plate, GB3531 08Ni3DR, 08Ni3DR 3.5%Ni steel plate, GB/T 713.4 08Ni3DR, 3.5Ni DR plate, is a ~3.5% nickel low-temperature pressure vessel plate under GB/T 3531 (moved to GB/T 713.4 in the 2023 succession), with typical Charpy at -100°C and yield about 320 MPa. Gangsteel (HENAN GANG IRON AND STEEL) produces and exports 08Ni3DR / 3.5% Ni plates for cryogenic and deep-cold pressure 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 08Ni3DR. Verify the contracted edition and purchase-order supplements before ordering.

FAQ about GB/T 3531 08Ni3DR Steel Plate

What is GB/T 3531 08Ni3DR steel plate?

It is a 3.5% Ni low-temperature pressure vessel steel under GB/T 3531 (Steel plates for low temperature pressure vessels). a ~3.5% nickel low-temperature pressure vessel plate under GB/T 3531 (moved to GB/T 713.4 in the 2023 succession), with typical Charpy at -100°C and yield about 320 MPa. Gangsteel lists the official mill/certificate grade as 08Ni3DR. See the full GB/T 3531 08Ni3DR page for chemistry and mechanical tables.

What is the yield and tensile strength of 08Ni3DR?

Minimum yield is about 320 MPa up to 60 mm and 300 MPa for 60–100 mm. 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.

What impact test temperature applies to GB/T 3531 08Ni3DR?

Charpy KV2 is typically -100°C / ≥60 J. Always state the required Charpy temperature and energy on the purchase order.

What delivery condition / heat treatment does 08Ni3DR use?

Normalized + tempered or quenched + tempered per edition / agreement. Nickel alloy heat treatment must match the PO.

How does 08Ni3DR compare with other GB/T 3531 grades?

All sit in the GB/T 3531 low-temperature vessel family (commercial buyers still search GB3531). Sister grades: 16MnDR / 15MnNiDR / 15MnNiNbDR / 09MnNiDR / 06Ni9DR. Hub: GB/T 3531 Steel Plate. Ambient/elevated GB carbon/alloy grades are under GB/T 713 / GB/T 713.2.

Is 08Ni3DR equivalent to ASTM A203 / EN 10028-4 nickel grades?

Approximate only. 3.5% Ni class is often compared with ASTM A203 and EN 10028-4 nickel steels (EN 10028-4 hub). Dual certification requires the stricter combined limits.

What mill certificate does Gangsteel supply for 08Ni3DR?

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.

What thickness can Gangsteel produce for 08Ni3DR?

Typical 6–100 mm under GB/T 3531 tables. Browse the GB/T 3531 hub for the full grade list.
