Delivery and application differences between 12Cr1MoV and 12Cr1MoVR steels

12Cr1MoV steel plate is delivered in annealing or high temperature tempering state, and quenching heating temperature (℃): 970; Tempering heating temperature (℃): 750.

12Cr1MoVR steel plate is generally delivered in the case of normalizing+tempering. According to the special agreement at the time of ordering, 12Cr1MoVR steel plate can also be delivered in the case of annealing or tempering. It can significantly improve the plasticity and impact resistance of steel and improve the anisotropy of steel.

12Cr1MoV steel is generally used after normalizing and high temperature tempering to make superheated steel pipes, conduits, coils and other corresponding forgings with operating temperature not exceeding 570-585℃ in high-pressure equipment.

12Cr1MoVR steel plate is mainly used for the manufacture of high-pressure boilers and vessels.
