welding flux ZT.SJ402

welding flux ZT.SJ402 : 1.Dry the flux at 300-350 for two hours before use Equivalent to AWS-5.17 F6A2-EL12 F7A2-EM12

ZT.SJ402 (welding flux)  In accordance with GB/T5293-1999 F5A0-H08A Equivalent to AWS F7AZ-EL8 DESCRIPTION:    ZT.SJ402 is a bonded flux of manganese silicon type acid welding flux , it’s alkalinity is about 0.7. It is spherical, size10-60 mesh and can be used on AC or DC power source. It provides good welding usability, its unique features include stable arc and bead appearance is smooth. SJ402 is a kind of fight rust welding flux and is not sensitive to greasy dirt , oxidize layer and the rust for welding place. The welding flux is good to fight tide and pellet strength high in welding course, flux’s consumpution is measured less. APPLICATIONS: It is suitable for welding sheet and medium thickness steel plate, sheet higher fast welding especially. In combination with H08A wire, it can weld ordinary steel structure and some low alloy steel column and pipeline. GUIDELINES FOR USAGE:1.Dry the flux at 300-350°C for two hours before use2.Completely remove rust,oil and dirt from the groove surface prior to welding. TYPICAL FLUX COMPOSITION RANGE(%) SiO2+TiO2 CaO+MgO Al2O3+MnO S P 35-45 5-15 40-45 ≤0.06 ≤0.08   TYPICAL MECHANCAL PROPERTIES OF (GB/T5293-1999.F5A0-H08A) Test Value óbMPa ósMPa 5% Akv(J)0°C H08A ≥400 480-650 ≥22 ≥34
