Ferritic steels-2

 

In comparison with austenitic steels, ferritic steels are not as easily welded. There is

significant grain enlargement in the HAZ, with carbides being precipitated at the ferrite

grain boundaries, resulting in embrittlement of the weld and reduction of its corrosion

resistance. This embrittlement introduces a certain risk of brittle cracking occurring as

the weld cools to the brittle transition temperature of the material at about 100-200

In addition, there is a risk of transverse shrinkage cracks in the weld metal as it cools and

stresses rise. These potential problems are countered by heating the area to about

400which reduces the temperature and stress gradients.
