Martensitic steels--1
If the workpiece is welded in the hot state and then heat-treated, there is a risk of
hardening cracks in the transformation zone. There is also a risk of brittle cracking, as
the material has a relatively high brittle transition temperature, and welding-induced
stresses in and around the weld zone are significant. In addition, there is a risk of
hydrogen embrittlement in the HAZ, particularly if damp electrodes have been used.
Further, if using a filler material of the same metal as the base material, there is a risk of
transverse cracks in the weld metal, and so austenitic fillers are often used to reduce this
risk. This also reduces the risk of brittle failure.
