[MW:11085] RE: 11080] SA-213 Gr.T91

Appears to be an error.  All UNS K90901 (“91” alloy) were to be changed to P-No. 15E with publishing of 2009 Edition. 

 

Use P-No. 15E

Dear Experts

 

What's the P.No. of Material Specification of SA-213 Gr.T91?

 

I refer Sec.IX 2010 Edition as per QW-422 - it's P.No.5B Gr.No.2

                                         as per Appendices-D - it's mentioned P.No.15E Gr.No.1

 

Which one is the correct?      

 

 

With Regards
