Submerge Wires (LSW-309/309L) and Flux (LSF30)

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.
