Hi
For piping material killed carbon steel material I'm asking for guide to chose between A672 B65 class 22 and A672 C65 class 22 can anyone one adress me please thanks in advance

Class A 672 B65 pipe is made from A515 Gr. 65 plates and C65 pipe is made from A516 Gr.65 plates.

C65 material will have improved notch toughness which will deter the progress of a fracture, hence it is better for situations where impact, reversing, or varying loads are present.
