Abstract

Studies on the weldability of 17-4PH stainless steel, in the 621 degrees C overaged condition, showed that Cr-eq/Ni-eq ratio higher than 1.5 resulted in primary ferritic mode of solidification in the weld metal. Post-weld aging treatment at 482 degrees C enhanced the strength of the weld joint with corresponding reduction in impact toughness of the weld metal while post-weld aging at 621 degrees C caused marginal reduction in strength of the weld joint with significant increase in impact toughness of the weld metal.
