Product Description
Quality assurance efficient metal welding flux sj301 with good quality

Standard Conforming: GB/T5293-1999F4A2-H08A
Equivalent to: AWS A5.17F6A0-EL12
Description and Applications
REFMAT Flux SJ301 is a type of silicon and calcium based agglomerated flux, the basicity of which is about 1.0(neutral), black gray spherical grains in appearance. Its grain size is 2.0-0.28mm (10-60 meshes). REFMAT Flux SJ301 is suitable for use with AC or DC power; filler wires connect with Positive Electrode while in DC, the maximum current can reach to 1200 amps. With stable burning arc, the flux provides very good weld bead appearance and excellent slag removal (the slag belongs to "short slag"). REFMAT Flux SJ301 especially suits for circular seam welding due to there is no molten slag fluxing down when welding circular seam of minor diameter.

Combined with appropriate SAW wires such as H08A, H08MnA, H08MoA, the flux is widely used in ordinary steel structures like boilers, pipelines. REFMAT Flux SJ301 is also used for multi-wires rapid welding, so it especially suits for double-sided single pass welding. The weld bead transitions smoothly when welding large diameter steel pipes.
