Chemical Composition of Weld Metal % (Typical)
C: 0.06, Si: 0.45, Cr: 0.5, Ni: 0.5, Cu: 0.4, Mn: 0.7
A low hydrogen, basic flux coated electrode on a low carbon mild steel core wire with an extruded moisture resistant chemically basic flux which has controlled iron powder addition. The moisture resistant coating gives a very low weld metal hydrogen levels. The electrode recovery rate in respect to the core wire is approx. 120%. Smooth arc, low spatter, easy strike and restrike. The electrode is mainly used for weathering steels containing a similar controlled addition & is claimed to offer a threefold improvement in corrosion resistance compared with plain C, Mn steels. The weld metal also resists preferential corrosion in sea water, particularly in arctic waters high in oxygen & salinity,
& has applications for welding micro alloys & carbon manganese steels in ice breaker vessels & offshore structures. Applications also include architectural structures, bridges & exhaust gas flues.
