Product Description

Description:
   SJ303 is a type of Si and Ca based agglomerated flux special for submerged arc overlay welding (SAW).Its grain size is 2.0-0.28mm (10-60 meshes). SJ303 is suitable for use with DC power; filler wires connect with positive electrode. With stable burning arc, the flux provides excellent slag removal and smooth weld surface with uniform edges.

   SJ303 is recommended for the transition layer of the corrosion resistant stainless steel in surfacing, combining with welding strips (the width of strips ≤75mm) such as H00Cr21Ni10, H00Cr19Ni12Mo2, etc.

Remarks
     1. Redry the flux at 300~350ºC for 2 hours before welding.
     2. Impurities such as rust, greasy dirt, moisture, etc. should be cleared from welding area.
