Submerged ARC Welding Flux AWS F7A0 EM12K

Agglomerated flux SJ501

Name of Submerged ARC welding flux: Agglomerated flux SJ501

Item No.: SJ501

Executive Standard : GB/T 5293-1999 F5A2-H08MnA (Equivalent to:AWS A5.17. F7A0-EM12K )

CHARACTERISTICS & FIELD OF USE:

• SJ501 is a type of aluminum and titanium base agglomerated flux, the basicity of which is 0.5 to 0.8 (acidic). The aluminum and titanium basic type and designed for making the steel pipe and welding general structural steels; pressure vessel & pipe steel & fine grain structural steels.

• The welding flux SJ501 is characterized by its low Si & moderate Mn pickup & is suitable for single & multi-wire welding as well as for welding by the two-run technique.

• It can be used on DC(+) or AC up to 1000 A. Its good welding characteristics allow it to be used for fillet welding & for welding at high speeds.
