Steel Q345R (HIC) is a Q345R pressure vessel plate with hydrogen induced cracking resistance test. Q345R(R-HIC) plate is based on Q345R (HIC) and SSCC test, namely sulfide stress corrosion test. The delivery status of Q345R (HIC) and Q345R Q345R(R-HIC) plate is normalizing, - 30 ℃ impact, level I flaw detection, process reference standard GB713-2014. sale 09CUPTIRE-A steel, Q345R (HIC) and Q345R (R-HIC) plates are smelted by electric furnace + refining outside the furnace. The smelting process is Ca-treated, and should be intrinsically fine-grained steel. The actual grain size is 5 or above.

40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. sale 09CUPTIRE-A steel, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.
