2013 ASME BPVC Section II, Part A, SA-20/SA-20M SPECIFICATION FOR GENERAL REQUIREMENTS FOR STEEL PLATES FOR PRESSURE VESSELS
13. Identification of Plates
13.1 Required Markings:
13.1.1 Except as allowed by 13.4, plates shall be legibly marked with the following information: applicable ASTM designation (see 1.1) (year of
issue not required); “G” or“ MT” if applicable (see 13.1.2); applicable grade, type, and class; heat number; plate identifier; and name, brand, or trademark of the manufacturer (for plates produced in discrete cut lengths of flat product) or the processor (for plates produced from coil and
for subdivided plates (see 13.4)).
13.1.2 Plates that are required to be heat treated, but have not been so heat treated, shall be marked, by the manufacturer or processor, with the letter “G” (denoting green) following the required ASTM designation mark, except that “G” marking is not necessary if such plates are for shipment, for the purpose of obtaining the required heat treatment, to an organization under the manufacturer’s control. Such plates shall have been qualified for shipment on the basis of test specimens that have been so heat treated. Plates that are required to be heat treated, and
have been so heat treated, shall be marked, by the party that performed the heat treatment, with the letters “MT” (denoting material treated) following the required ASTM designation mark.
2013 ASME BPVC Section Ⅷ, Division 1
UG-85 HEAT TREATMENT
When plate specification heat treatments are not performed by the material manufacturer, they shall be performed by, or be under the control of, the Manufacturer who shall then place the letter “T” following the letter “G” in the Mill plate marking (see SA-20) to indicate that the heat treatments required by the material specification have been performed. The Manufacturer shall also document in accordance with UG-93(b) that the specified heat treatment has been performed.
ASME  材料 SA-516 Gr70，由压力容器制造厂正火后如何标识？
答：钢厂提供的钢板标记 SA-516 Gr.70 G
      压力容器制造厂正火后的标记 SA-516 Gr.70 GT
      而不是上面说的 SA-516 Gr.70 N.

應該是ASME SA516 Gr70N

查看SA-20 13.1.2条款。容器制造厂完成正火后，在钢板上补喷“MT”字样即可。
个人理解，期待高手赐教。

看规范，钢板制造厂与容器制造单位应有区分

压力容器正火后，容器标识要做转移，制造厂负责，产品有所体现：
钢板正火标识，做入厂验收时可见
