PROPERTIES OF THE METAL OF THE HEAT AFFECTED ZONE IN MARAGING STEELS

In the welding of heat-treated (quenched plus aged) maraging steel, softening of the HAZ metal occurs under the action of the welding thermal cycle. The degree of softening is almost independent of arc power for welding with a linear heat input in the range 1000 to 8000 cal/cm, because under these conditions the process of softening is governed mainly by the temperature. In multipass welds there is increase of the strength of the softened HAZ metal as a result of further aging through deposition of the subsequent beads and the effect of contact hardening of the soft interlayer.
