metallographic structure and temper embrittlement tendency evaluation of 150 mm thickness SA387Gr22C12 steel plate( /% : 0. 13 ~ 0. 14C
0. 09Si
0. 55 ~ 0. 56Mn
0. 004P
0. 001S
2.48 ~2. 49Cr
1.11~1. 12Mo ) are tested. The each property of steel plate with delivered state (normalizing + tempering )
minimum simulated post-weld state
maximum simulated post-weld state and step cooling test are measured. The results show that the temper embrittlement tendency of steel plate is not obvious
the resulf of CvTr55 +2. 5 Δ CvTr55 is -63 ℃
fully to meets the technical requirements of steel plate for methanol synthesis tower.
