  2. P91 and Beyond - Lincoln Electric

    ifferences in hardness between the base metal, weld metal, and HAZ for a P91 weldment are shown in Fig. 1. This trend for the HAZ to be a soft zone exists with all the CSEFs. Given that hardness can be an in-dicator for strength in low-alloy materi-als, the HAZ offers the least performance, regardless of the weld metal or base metal involved.

    base steels, the Ac1 temperature of T/P92 is higher than that of T/P91. The measuredAc1 values of P92 weld metals followed the same trend. With a similar level of Ni+Mn, theAc1 temperature of P92 weld deposit is 10°C to 15°C higher than that of P91 weld deposits. This agrees with the results from thermal dynamic calculations [9].
