[MW:6663] What is the Filler metal to weld Base metal (SA516 Gr 60) to achieve weld metal tensile properties after Normalization+ Stress Relieving

Dear All, We are getting Heads for pressure vessels from Supplier in Saudi, The head requirements are as follows:   Head: 28mm thk; SA516 Gr 60, NACE MR 0175 & HIC tested NACE TM 0284 Construction Code ASME SEC VIII Div 1, E2007 Ad2009. Type of Head Ellipsoidal with chordal seam (U stamped) Service For Pressure vessel in Sour Service HT: Normalization at 910deg C for  after forming & SR at 610 deg C along with vessel. Chemistry restriction by Client: C= 0.06% Si=0.24%, S= 0.007 & P=0.015, Hardness 200BHN Simulation Testing for HT (NR+SR) on test plate required.     Now the supplier has submitted me WPS / PQR for welding chordal seam of head for my review, the details of PQR as follows: Base metal SA516 Gr70; 90mmthk SMAW with E9018-G; SFA 5.5; A=10; F no. 4 SAW with F9P6 EG F3; SFA 5.23; A=10; F no. 6 HT= NR+SR   The weld metal composition achieved on PQR for SAW process are C=0.06%, Mn=1.37%, Si=0.24%, S% <0.005, P=0.014%, Mo=0.48%, Ni=0.82%, Cu=0.13%.   Tensile& bend test meeting requirements of Base metal.   My Question is whether the proposed filler metal is acceptable to this base metal (SA516 Gr 60) as per ASME SEC IX as weld metal chemical properties are not meeting the base metal requirements.   Thanks for co operation in this regard   Aly Kuwait
