[MW:12842] SA 516 Gr 70 HT requirement

Dear All,

If the material required is SA 516 Gr 70 N and the material received
is completely satisfying the requirement but the marking observed on
plate is without "N" or "MT". Can we accept the material for Code
stamped vessel??

My interpretation of the code requirement is,

As per SA 516 Para 13.1.2, marking should include MT also.

Please advice whether MT is inclusive of Normalizing.

Regards

Akhil
