SJ106 is a kind of high basicity, fluoride-alkaline-type sintered flux, off white round grain. Grain size: 10-60 mesh. Basicity: 3.0. It has a good welding procedure, good weld joint and excellent high temperature slag removing. There is no Mn and Si transfer in weld metal. It's adopt DCEP powder and matching low carbon steel low alloy steel austenite steel and steel wire in multiple-layer welding. The weld metal have mechanical property and high low temperature impact toughness, it is used for bead welding in matching proper wire have good high temperature oxidation resistance and wear resistance capability.
Cautions:
1.The oil soil,moisture,iron and other foreign substances must be removed from the welding joint.
2.The welding flux must be baked under 300-350ºC for 2 hours.
