Question

9.3 A 304 stainless-steel sheet with a composition given below is welded autogenously with the GTAW process. The shielding gas is Ar-2% N2, and the nitrogen content of the weld metal is about 0.13%. The contents of other alloying elements are essentially the same as those in the base metal. (a) Calculate the ferrite numbers for the base metal and the weld metal. (b) The weld metal exhibits the primary solidification phase of austen- te, and the ferrite content measurements indicate essentially zero
