Dear experts,...

I need to qualify a PQR for SA 335 Gr P9 pipe welding. We have plate SA 387 Gr 9.

But I don't find P number allocated for SA387 Gr 9, and UNS number is matching. Can we consider the P number as 5B?

Someone may object that it is unlisted material??

Please advise and share your thoughts on this why this particular plate grade is not listed in p number table.

With regards,

SATHEESH KUMAR.P
