Cr and Mo in 12Cr2Mo 1R are abbreviations of chemical elements chromium and molybdenum, and R is the capital letter of the container.
12Cr2Mo 1R belongs to a large category of steel plates-hydrogen-resistant steel, corresponding to foreign brands ASTM/SA387Gr22CL2.
The main steel grades of hydrogen-resistant Cr-Mo steel in Wugang are 14cr 10r steel plate for coke tower, SA387GR 1 102 steel plate for gasifier, 2.25Cr- 1Mo steel plate for hydrogenation reactor and large-thickness hydrogen-resistant steel plate.

12Cr2Mo 1R has three densities: true density, quasi-density and effective density. What role does it play in 12Cr2Mo 1R material?
1. Before casting 12Cr2Mo 1R steel, the factory needs to estimate how much metal needs to be melted, and the required metal amount can be calculated according to the mold volume and the steel density of12cr2mo1r.
2. Calculate the volume of 12Cr2Mo 1R steel, which is difficult to weigh and has complex specifications or shapes.
3. Identify the unknown components in 12Cr2Mo 1R steel.
The density of 12Cr2Mo 1R steel is related to the added alloy composition. As long as the composition of 12Cr2Mo 1R alloy steel is known, the density of 12Cr2Mo 1R steel can be calculated with a small error.
