Welding flux HJ431 is a kind of high manganese oxide and SiO2,CaF2 smelted flux.
it is a kind of granule red brown to light yellow color;
the size is about 2.5 ~ 4.0mm ( 8 mesh ~ 40mesh); and 1.5mm ~ 1.8mm ( 14mesh ~ 80 mesh );
when used on AC or DC+. It is good at welding and weld-ability;
Application of High Silicon manganese oxide selted flux:
In combination with Welding wire EL12; EM12K; EH14. this conbination is suitable for welding LOW ALLOY STEEL, HIGH STRENGTH STEEL( 16Mn, 15MnVN) , the important structures, the fabrication of ships, boilers and pressure vessels etc.
The chemical of welding flux:
Mn+SiO2: 74 ~ 82 %; CaF2+CaO : 10 ~ 14 %; MgO + Al2O3 : 9 ~ 12 %; low S.P.
The mechanical of welded metal:
Yield Strength : 388 MPa;
Tensile Strength: 500 MPa;
Elongation: 30
Usage of Guiding:
Dry the flux at 250C for two hours before used;
Completely remove rust. oil and dirt from the proove surface prior to welding;
