Product Introduction
309L is an ultra-low carbon 24Cr-13Ni austenitic stainless steel TIG welding wire protected by pure argon gas. It has excellent welding processability, stable arc, no spatter, and beautiful weld formation. It can be used for all-position welding, has good crack resistance, and is suitable for welding martensitic and ferritic stainless steels with poor toughness. It can also be used for welding 022Cr24Ni13, and its common applications are in petrochemical and other fields.
