Name of Item: Medium-Manganese-Oxide Fused Flux LHHJ350
Executed Standards: GB.T12470-2003:F48A4-H10Mn2;
(equal to: AWS A5.23- F6A0-EH14 , JIS YSF-W41)
Specification of Fused Flux :
LHHJ350 is a medium manganese-oxide fused flux with vitreous granule of red-brown to light yellow color, grain size about 8~40 mesh (or 14 ~ 80meshes) in two sizes.It is suitable for welding with AC and DCEP, and it shows good Welding ability.
Application of flux :
For the combination with H08MnA,H10Mn2,H08Mn2Mo welding wires,
the flux is designed for welding of low alloy steel (such as16Mn,15MnV ) important steel structures,ships,boilers, high pressure vessels.
The small size 14~18meshes flux is recommended for welding of thin plates.
