Wugang low temperature vessel plate 16MnDR

16MnDR It is a kind of steel plate for low temperature pressure vessels ;16Mn— Indicates that the carbon content in the steel plate is about 0.16%,D- Indicates low temperature ,R- Means pressure vessel ( Generally, when the content of a certain chemical element in steel is high, it should be indicated in the material , such as 1.6% You can write 16Mn),16MnDR Is used for -40 Steel plates for pressure vessels .16MnDR The steel plate is normalized , Plate thickness 6-36mm The minimum operating temperature is -40°, Plate thickness 36-100mm Minimum operating temperature -30°.

16MnDR The delivery status is normalized, and the flaw detection is above level 3 ; Executive Standards ：GB3531.
