Abstract

The countermeasure for improvement of the bend ductility of the low interstitial ferritic stainless steel overlay welds has been investigated.
The addition of stabilizing elements, especially zirconium, up to about 0.4% to the first layer of the ferritic stainless steel overlay welds with 30% chromium on a low alloy steel improved its bend ductility. The bend ductility of the overlay welds was also improved with decreasing the chromium content in the first layer of the weld metal.
On the basis of these results, a composition of 19Cr-2Mo-0.25Zr-Fe was recommended for the filler metal for the first layer of the 30Cr-2Mo steel overlay welding on a low alloy steel in order to ensure a good weld ductility.
