Filler wire for P92 also is usually modified for reasons explained later. P92 and T23 are strictly ASTM-ASME designations for pipe and tube respectively of alloy grades 92 and 23, which are currently the forms most widely used.See all results for this questionWhat's the difference between p92 and T23 steel?P92 is a modification of P91 with 2%W replacing most of the Mo, and T23 is a low carbon 2.4%Cr steel alloyed with W, V and Nb. Microalloying with up to 0.006% (60ppm) boron is also important for both alloys (specifications are tabled later with weld metals).See all results for this questionWhich is the best arc welding process for p92?Traditionally GTAW, SMAW, FCAW and SAW are the most widely used arc welding processes and all of these could be applicable to P92 and T23.
