Sandvik 19.9.NbSi Welding wire
Categories:	Metal; Ferrous Metal; Alloy Steel
Material Notes:	Sandvik 19.9.NbSi is a filler metal particularly suited for MIG welding. It can also be used for TIG and plasma arc welding. It is suitable for joining stainless steels of the 18Cr/8Ni/Nb and 18Cr/8Ni/Ti types. Due to the strengthening effect of niobium, this grade is recommended if the weld metal is exposed to temperatures above 400°C (750 F). Information provided by Sandvik
