SJ101


详细

Name of Item:  Agglomerated Flux LHSJ101  

Executed Standards:  GB/F4A4-H08AMnA; F5A2-H10Mn2; NB/T47018.4-2011;
                       (Equal to: AWS / F7A2-EH14 ; F48A2-EH14 ); 

Specification of flux:
LHSJ101 is a kind of high- basic welding flux with Fluorine-Basicity slag series,
It has good Sulfate and Phosphate removal and antirust ability. The welded metal has good toughness and high anti-

coldness and anti-cracking quality. it has good slag detachability even for the narrow gap and deep groove welding.

Application of flux:
For the combination with the welding wire H08A; H08MnA; H08MnMoA ;H08Mn2.
( DIN 8557 S1;S2;S2Mo,S4 or AWS. EL12;EM12K;EA1;EM14), The flux is designed for welding of low alloy steels for

important products, such as boilers, pressure vessels, pipelines etc. it is also suitable for multiple wire sub-arc

welding, especially for butt welding of large diameter vessel with one-pass on both sides. Also, it can be used for

the quick welding of steel pipe.
The composition chemical of flux( %): Basicity= : 1.6-1.8;
SiO2+TiO2: 15-20;   CaO+ MgO: 25-35;  Al2O3 +MnO: 25-30; 
CaF2+FeO: 15-20;  S:0.03 max;        P:0.03max;
