For Piping,for High temperature applications we select ASTM A106 Gr.B & for low temperature applicable one may select ASTM A 333 Gr.6. This is only an example.
The Chemistry and Heat Treatment requirement shall comply with the Applicable Material standard/specification like A106Gr.B or A333 Gr.6.
If the Heat number is same and all the requirements of the specifications are complied, then it is considered acceptable.
