Kindly advice me which the fitting material is better A234 or A694 Gr.F52 in welding with pipe’s materials A106 Gr.B and API5L PSL2 Gr.BNS NACE from the side of weldability and corrosion resistance (knowing that we used Er70S-3 for the root and hot passes and E6018 for the others? and what happened to the mechanical properties for the A694 Gr.F52 if we want to do PWHT after welding? 
I didn't find the right solution from the internet.
