Product Description

Submerged Arc Welding Flux (HJ431AWS F6A2-EL12)

 

Fit	NB/T47018-2011	GB/T5293-1999	F4A3-H08A	F5A2-H08MnA
Equivalent to	AWS-A5.17		F6A2-EL12	F7A3-EM12K

1.It is a kind of high manganese and silicon, low fluorine fused flux.



2.Fused flux produced by Laiwu Taishan Sunlight Welding Materials Co., Ltd. ISO9001 certified factory.



3.Color: red brown to light yellow.



4.Grain size: of 8-40(2.5-0.38mm) and 14-40(1.5-0.38mm) meshes.



5.Current: alternating or direct current(welding wires must be connected with the positive


electrode when direct current is used).




Standard Packing:



Kraft bag with anti-moisture plastic lining inside. Plywood pallet



25kg/bag, 40bags/Pallet, 24 Pallets in 20'GP container.



Gross weight: 24,240 kg



Total size: 24CBM




Usage:

1. For low-carbon and low-alloy steels like 16Mn and 15MnV, as well as ships, boilers and high-pressure



vessels[applied to welding wires such as H08A(AWS EL8), H08MnA(AWS EM12) and H10MnSi(AWS

EM13K)] 



 2.for electro-slag and copper welding.




Cautions:
   

1.The oil stain, moisture, iron rust and other impurities must be removed from the surface.
   


2.Flux must be baked under 250~300°C for 2 hours before welding.




Applications:



Butt and flat fillet welding of miniature LPG tanks, ships, vehicles, agricultural



implements, machinery, boilers, bridges, structural steels.
