12Cr2Mo1VR steel plate technical standard:
The size, shape, weight and allowable deviation of the 12Cr2Mo1VR steel plate shall comply with the provisions of the GB/T 709 standard.
The thickness deviation of 12Cr2Mo1VR shall be carried out according to Class B or Class C of GB/T709.
12Cr2Mo1VR 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.
