16MnDR is a kind of low-temperature pressure vessel steel plate. 16Mn-indicates that the carbon content in the steel plate is about 0.16%, D-indicates low temperature, and R-indicates pressure vessel. (Usually, when the content of a chemical element in steel is high, it needs to be indicated in the material, for example, 1.6% manganese is written as 16Mn. 16MnDR is a steel plate for pressure vessels at -40 degrees Celsius.
Delivery state of 16MnDR: 16MnDR delivery state normalised above three levels of flaw detection, positive plus back.
16MnDR probing inspection: Thickness greater than 20mm steel plate, the supplier should make ultrasonic flaw inspection sheet by sheet, the thickness is not greater than 20mm, by mutual agreement, the supplier can also make ultrasonic flaw inspection.
