Note: EN/DIN Norms are not mentioned in this survey as there is no such thing as an equivalent matching chemical composition 100%.
 
A508 Gr.3 Cl.1 might be used for the German WB36. A350 LF2 could be used instead of P280GH.
In every case the proper ASTM/ASME/AISI material grade has to be discussed.
