Beschreibung
Zusammenfassung:	PURPOSE:To improve the corrosion resistance in nitric acid and to extend the service life of the above member by composing the base metal consisting of an austenitic stainless steel in such a manner that the weld metal formed by melting and solidifying of the base metal has the solidification form to first crystallize a delta ferrite phase at the time of solidification. CONSTITUTION:The compsn. of the base metal of the austenitic stainless steel consists, by weight, of
