AWS A5.9 ER309/309L
JIS Z3324 S309/309L
▶︎ Characteristics:
LSF-30 is an agglomerated flux adding proper contents of alloying element to maintain the stability of the contents of ferrite in weld metal. It is designed for welding with stainless steel 309/309L to gain characteristics of great crack and corrosion resistibility and mechanical property. With good weldability, slag removal, stable arc, smooth bead appearance and welding efficiency.
▶︎ Applications:
It is suitable for welding of stainless steel 309/309L.
▶︎ Notes on Usage:
1. Dry the flux at 300-350℃ for 60 minutes before use.
2. To get the corrosion resistibility and mechanical properties on heat effect zone, recommend to use low heat input.
