16MnDR Container Steel Plate
16MnDR is a kind of low-temperature pressure vessel steel plate, executive standard: GB3531.
16Mn-indicates that the carbon content in the steel plate is about 0.16%, D-indicates low temperature, R-indicates pressure vessel. (Usually, when the content of a chemical element in steel is high, it should be indicated in the material, for example, 1.6% manganese is written as 16Mn), 16MnDR is a kind of steel plate for pressure vessel at -40℃.

16MnDR Boiler Plate Steel size, shape, weight and allowable deviation
The size, shape and allowable deviation of the steel plate should be in accordance with the provisions of GB/T709.
Thickness deviation of steel plate should be in line with GB/T709 class B deviation requirements, according to the requirements of the demand side, can also be GB/T709 class C deviation delivery.
The steel plate shall be delivered according to the theoretical weight, and the density of steel plate for calculation is 7.85g/cm³.
16MnDR pressure vessel plate Ultrasonic Inspection
16MnDR pressure vessel steel plate thickness greater than 20mm normalized or normalized and tempered state delivery of steel plates and thickness greater than 16mm quenched and tempered state delivery of steel plates should be ultrasonic testing, other thicknesses of steel plate by the supply and demand sides can also be ultrasonic testing of each sheet by negotiation, the detection method in accordance with the JB/T4730.3 or GB/T2970 implementation.
