Solid Wire Rod BA-TIG 316LSi for TIG Welding
Classification:
EN ISO 14343-A: W 19 12 3 LSi
SFA 5.9 / AWS A5.9: ER316LSi
Main Application
BA-TIG 316LSi is a solid wire rod for GTAW with higher Si content than BA-TIG 316L, suitable to weld austenitic stainless steels grades 1.4401 / 316, 1.4404 / 316L, 1.4435 / 316L. Suitable for service temperature from -120°C to + 400°C. Also suitable for the welding of grades 316Nb or Ti stabilized (347 and 321) if service temperature < 400 °C.
