描述
特点
LSF-340 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 347 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
应用：
It is suitable for welding of stainless steel 2209.
使用说明：
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.
