Conforming to：GB /T5293 F4A2-H08MnA F5A4-H10Mn2
Equivalent to： AWS-A5.17 F7A2-EH14 F7A2-EM12K F7A2-EA2-A2
DIN BFB 165AC12MHP5
Description and application
Semi-Basic, agglomerated flux for welding of essential structural steel in combination with appropriate SAW wire (such as EH14,EA2, EM12K etc.). Weld bead hardly increases Si and Mn, it belongs to metallurgy neutral. It has perfect welding performance, stable arc, good surface, excellent slag removal, high impact toughness at low temperature. The filler metal should be connected to Positive when DC. SJ101 can be used for many applications ranging from boilers to pressure vessel, pipeline and low alloy steel structure.
• Flux type: Fluoride-Basic

Remark
1. Before welding, fluxes should be baked for two hours at 300-350℃.
2. Removal of rust, oil, dirt, water, impurities, etc in welding-areas.
