A-53B is not in the same category.

I don't know what any of that means. Normalizing as it applies to carbon steel refers to heating so the entire structure reverts to austenite, then cooling at a sufficient rate to produce a fine-grained structure.
Finer grain size is the only important strengthening mechanism that can also improve fracture toughness.

Stanweld, I misread, I understand it is not Gr B 5L pipe, but you should not be using A53 Gr A for most piping applications.
As far as grade of of material, these materials are good mettalurgical replacements, however neither are recommended for 36" pipe per ASTM.

itstru58: what is the wall thickness and maximum pressure the pipe will operate? What is the application, i.e. water, gas, oil, construction code (API 1104, ASME IX,), etc.

For your stated design condition, normalized pipe is not necessary.
