[MW:17424] SA516 Gr70 plates having different markings are acceptable for ASME ustamped Pressure Vessel


Dear Experts

We wanted to use SA516 Gr70 plate from DANSTEEL (MTCs' are attached) where original marking on plate is as follows

UR

LR EH36 S355K2+N CE; refer the attachment

(SA516 65/70MTLTV is not punched on plate; but the marking on plate is traceable to given mtc…

Mtc shows Specification as ASME SA516 65/70 LR EH36 S355K2+N

Mill has issued letter regarding modification of marking as ASME SA561 65/70 MT LTV…(refer attachment)

We internally released these plates as marking on plate is traceable to MTC…further there is letter from Mill regarding the marking.

Kindly advise can we use this plate for ASME U Stamped Pressure vessel job
