1.Specifications:

 EN760 SA FB 2 55 AC H5     

2.Description:                                                   
SJ102 is an agglomerated fluoride-basic type flux. B‖W=1.6,mesh 10-60,the shape is gray-white round grain.It can assure very pure weld metal,very low level of residue elements in all-weld which will perform excellent resistance to crack. The slag removal is easy at high temperature,with smooth and defect free weld bead appearance.

It should be re-dried under 300-350℃ for 2 hours. Rust,grease and moisture on the weldment should be removed before welding.

3.Applications: 
For surfacing/hardfacing/cladding of rollers for continuous casting,steel rolling,transporting,and also some kinds of wearproof materials,etc.

The flux is suited to combine with high alloy wire(sold wire or flux-cored wire),such as 414,414N,410NiMoV,and 13%Cr series of flux-cored wires or sold wires.
