GB/T 3531 09MnNiDR Steel Plate | 09MnNiDR Low-Temp Plate

GB/T 3531 09MnNiDR steel plate, also written as 09MnNiDR pressure vessel steel plate, GB3531 09MnNiDR, 09MnNiDR low-temperature steel plate, GB/T 713.3 09MnNiDR, is a low-carbon Mn-Ni pressure vessel plate under GB/T 3531 / GB/T 713.3 for deeper cold service, with typical Charpy at -70°C and yield about 300 MPa in the thin band. Gangsteel (HENAN GANG IRON AND STEEL) produces and exports 09MnNiDR plates for -70°C-class low-temperature vessels and storage equipment.

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 09MnNiDR. Verify the contracted edition and purchase-order supplements before ordering.
