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:
When applied with welding wires such as H08A, H08MnA, H10Mn2 or H10MnSi, HJ431 can weld low-
carbon steel and some low-alloy steel like 16Mn and 15MnV, as well as LPG tanks, ships, boilers and
low-pressure vessels, Structural steels, etc.
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.
