Solid Wire Rod BA-TIG 318Si for TIG Welding
Classification:
EN ISO 14343-A: W 19 12 3 Nb Si
SFA 5.9 / AWS A5.9: ER(318)
Main Application
BA-TIG 318Si is a solid wire rod for GTAW, suitable to weld 19Cr/12Ni/3Mo stabilized Ti grades like 1.4571 / 316Ti. Also suitable for the welding of similar unstabilized grades 316 or 316L. BA-TIG 318Si is suitable for service temperatures from -120 °C to +400 °C and has high resistance to intergranular corrosion.
