Compositions of fluxes (%)

SiO2+TiO2	CaO+MgO	Al2O3+MnO	CaF2	S	P
18-25	28-35	23-30	16-25	≤0.06	≤0.08

Typical all weld metal mechanical property

Wire	Yield Stress	Tensile Strength	Elongation	AKV(J)
H10Mn2(EH14)	≥375Mpa	490-660Mpa	≥22%	≥27/-40°C

Remark

1.      Before welding, fluxes should be baked for two hours at 300-350°C.

2.      Removal of rust, oil, dirt, water, impurities, etc in welding-areas.
