Subject: Re: [MW:7103] F-No&A-No of ERNiCrMo-3
Dear Raghuram sir,
I have reviewed my WPS and the following values observed.
Specification (SFA) : A 5.14(GTAW)
AWS classification : ER-NiCrMo-3(GTAW)
Trade Name : Thermanit625(GTAW)
Filler metal product form : Solid (GTAW)
Chemical composition in % for GTAW: C-0.008%, Si-0.06%, Mn-0.02%,Cr-22.32%,
Mo-8.93%, Nb-3.53%, Ni-64.10%,Fe-0.439%,P-0.001%,S-0.001%,Cu-0.039%,Ti-0.181% &Al-0.127%
Dear Karthik Sir,
Thank you for the correction,I had mistakenly typed QW.422 instead of QW.442
I have reviewed ASME QW.422 'A' No. section and couldn't find any matching chemistry with above mentioned chemical composition.
In this case,In the A-No column of WPS, what I have to write? N/A or Nil?
Regards,
Limesh

Hi, P.Number and F number are different and the numbers cannot be same and substituted. For ERNiCrMo-3 F-Number is 43. For A number You can check with the QW-442 along with your Filler metal certificate to compare the chemical composition.Since it is a nickel based alloy,you check with the composition of A number 10 requirments. Pls.find below the extraction of ASME appropriate sections.
Dear All, I want to prepare a WPS for , material ASTM B 423 (P No-45). Process - GTAW Construction Code - ASME B31.3 Welding Code - ASME BPV SEC IX What is the F - No. of ERNiCrMo-3? 43 or 45?One of the WPS in my hand says 45 !!! I have reviewed ASME BPV SEC IX QW 432,F-No. section and found that 43.Now I need clarification from experts,which one is correct 43 or 45? What is the A - No. of ERNiCrMo-3? I have reviewed QW 422 A-Numbers section,but couldn't find. Is there any condition that P- no. and F- no. shall be same? Seniors, I need your help on this issue. Regards, Limesh |
