Generally, 12Cr1MoVR pressure vessel steel plate thickness is within range of 6mm - 100mm. 12Cr1MoVR steel plate shall do impact test at 20℃ with the impact energy no less than 47J. 12Cr1MoVR steel plate is delivered in normalizing and tempering state. The tempering temperature of 12Cr1MoVR pressure vessel steel plate shall not be lower than 680℃. With the agreement of the demander, 12Cr1MoVR pressure vessel steel plate thicker than 60mm can be delivered in annealing or tempering state, or delivered in the condition of accelerated cooling and tempering after normalizing.
