1.JN-HJ431 is a kind of high manganese and silicon, low fluorine fused flux

2.Color: red brown to light yellow

3.Grain size:of 8-40(2.5-0.45mm) and 14-40(1.5-0.45mm) meshes

4.Current:alternating or direct current (welding wires must be connected with the positive electrode when direct current is used)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 surface2.Flux must be baked under 250~300°C for 2 hours before welding.
