Sandvik 19.12.3.LSi Welding wire
Categories:	Metal; Ferrous Metal; Alloy Steel
Material Notes:	Sandvik 19.12.3.Nb is a niobium stabilized filler metal suitable for joining stainless steels of the 18Cr/8Ni/Mo, 18Cr/8Ni/Mo/Ti and 18Cr/8Ni/Mo/Nb types. Due to the strengthening effect of niobium, this grade is recommended if the weld metal will be exposed to temperatures above 400°C (750 F). Information provided by Sandvik
