What are the differences between 12Cr1MoV and 12Cr1MoVG, these two materials?

12Cr1MoV is an alloy structural steel that can be made into pipes, sheets, strips, forgings, castings, rods, etc. 12Cr1MoVG is a type of pipe made from 12Cr1MoV alloy structural steel, with G referring to boilers. Mainly used for steel pipes in boilers.

The second floor is correct; adding G refers to steel used for boilers

The standards vary: 12cr1mov follows the 8162 standard, while 12cr1movG follows the 5310 standard. The version with G undergoes normalizing and tempering processes in addition to those applied to the version without G. The new 2017 version of high-pressure boiler tubes also specifies requirements regarding hardness; the chemical composition remains the same. The 8162 standard is more commonly used in the manufacture of pipe fittings
