Correspondence between ship plate strength grade and carbon steel

The 32-level ship plate strength should be between Q275 and Q345. The lower yield of Q275 is 275, the lower yield of Q345 is 345, and the upper yield of grade 32 ship plate is 315 (closer to the cancelled Q295).

The 36-level ship plate corresponds to Q345. The A36-level ship plate is closer to Q345C, the D36-level ship plate is closer to Q345D, and the E36-level ship plate is closer to Q345E.

Class 40 ship plate corresponds to Q390. The A40 class ship plate is closer to Q390C. The D40 ship plate is closer to Q390D. The E40 ship plate is closer to Q390E.
