30CrMo steel plate smelting method, chemical and mechanical properties

30CrMo steel plate smelting method:
Converter / electric furnace steelmaking → LF furnace refining → VD furnace vacuum degassing → continuous casting / die casting / electroslag → cleaning and heating → rolling → flaw detection → heat treatment → steel plate finishing → sampling → performance inspection

Melting analysis of chemical composition of 30CrMo steel plate:

Grade	C	Si	Mn	P	S	Ni	Cr	Mo	Cu
30CrMo	0.26-0.34	0.17-0.37	0.4-0.7	≤0.035	≤0.035	≤0.3	0.8-1.1	0.15-0.25	≤0.3

Composition notes: Cu and Ni are residual elements.
