Hello, fellow marine engineers. I work in the field of hydrogenation processes, and I have a question for you: what is the difference between 2.25Cr1Mo and 12Cr2Mo1 in chromium-molybdenum steel? These materials are often used in reactors, and I’m not quite sure what the differences are; what are their advantages and disadvantages? Thank you all; please feel free to share your advice! ! !

The explanation on the first floor was excellent; 12Cr2Mo1R can be used as a substitute for SA387GR22CL2.

We all use 15CrMoR; it seems that 12Cr1Mo can achieve higher performance than it, but I’m not sure about the other options

2.25Cr-1Mo is the designation in American standards. That is, the pile of materials P22 F22 B22 FP22 T22 inside. .

Does anyone know where I can buy this type of steel plate, with a diameter of around 2 meters and a thickness of about 11 cm?
