Agglomerated Flux HF**1G 


 Agglomerated flux LH-HF**1G
( for: Submerged Arc Welding Flux.)
 
Execute standards: GB/T **********- F*8A*-H*0Mn2A;        
( Equal to the standards: AWS F7A*-EH*4; F7A*-EM*2K )    
 
Description: Agglomerated Flux LH-HF**1G is kind of special sintering flux with High Basicity 2.0; it is the grey spherical grain, Size of *0mesh to *0 mesh. The weld slag is easy to be removed on the welded position. The welding bead has the high impact tenacity at low temperature.  
 
Application: it is suitable for making the important steel structure, high strong steel structure, Chemical pressure vessel and nuclear vessel and various steel pipeline such as API pipeline type of X*0;X*0 pipeline. It also can be used in multilayer welding, single-welding line with two sides, narrow gap SAW welding voluntarily. the LH-HF**1G flux shall need to combine with SAW wire(eg.: H*0Mn2A H*8MnMoA;;H*8Mn2MoA, EH*4,EA1,EA2).
