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.
