Explanation: JH-SJ403 is a silicon-manganese type agglomerated flux for overlaying welding, alkalinity around 2.2 It can be operated with AC and DC.It has strong rust resistance properties,not sensitive to the impurities of oxide film,oil,etc.
　　Applications:Accompanying with YD137 to conduct repair welding of lead wheel and supporting wheel of heavy-duty bulldozers.It can also be used with H08A wires to weld normal structure steels and some low alloy steels.

　　Chemical Composition of Flux

　　Mechanical Properties of Deposit Metal

　　Points of Attention：
　　1 The  fluxs  to be dried 2 hours in 300℃~350℃.
　　2 De-rusting, water and oil cleaning ,as well other impurities removing of the work be done before welding.
