16MnDR - GB /T 713.3-2023

Grade	16MnDR
Corresponding Standard	GB /T 713.3-2023 Steel Plate, Sheet and Strip for Pressure Equipments— Part 3: Low Alloy Steel with Specified Low Temperature Properties
Classification	Alloy Steel

16MnDR Chemical Element Composition Content (%)

Component	C	Si	Mn	P	S	Ni	Mo	N	Al
Minimum Value	-	0.15	1.2	-	-	-	-	-	0.02
Maximum Value	0.2	0.5	1.6	0.02	0.01	0.4	0.08	0.012	-

• When acid-soluble aluminium (Als) is used instead of Alt, the Als content should be no less than 0.015%. When the Nb+V+Ti content in steel is ≥0.015%, the Al content is not required.
