Is the forging used for Q370R 16Mn?
Thread Content
May I ask if the forging corresponding to Q370R is 16Mn?
Comparing NB/T 47008 and GB 713 standards, the chemical compositions of 16Mn forgings and Q370R overlap to some extent, but the requirements for the P element are stricter in Q370R. As for how to match steel plates with forgings one by one, we’ll have to wait for an experienced expert to answer that!
I remember that 16Mn corresponds to Q345R, :lol:lol:lol
Q345R was originally called 16MnR; accordingly, the corresponding forgings are 16Mn
16Mn is more commonly used in place of Q345R; I haven’t encountered Q370R yet. I’d appreciate some advice.
I have never used Q370R. However, in terms of strength matching, 20MnMoNb is closer to Q420. Would forgings made of 20MnMo be more suitable for Q370?
Personally, I think 20MnMo is more suitable, as their allowable stresses are relatively similar.
For 20MnMo, all the spherical tanks designed by our company are matched in this way
Can Q370R plates be used in combination with 16Mn forgings?
