Welding flux(SJ301) Conforming to: GB/T5293 F4A0-H08A F5A0-H08Mn2
Welding flux(SJ301) Equivalent to: AWS-A5.17 F6A0-EL12 F7A0-EM12K DIN BSC 198AC 10SKM
Welding flux(SJ301) Description:
SJ301is a kind of silicon-calcium sintered flux, mesh 10-40(that is 1.7-0.38mm) and
the basicity is 1.0-1.1. Either alternate or direct current can be used, while the welding wires
must be connected with the positive electrode when direct current is used. Produced with excel-
lent technology, the flux has the properties of fine slag detachability and fine welding bead
appearance.
Welding flux(SJ301) Usage:
The flux is fit for the submerge-arc welding of low-carbon steel and low-alloy steel, as well
as the fast single-way and double-surface welding of thin steel sheet. And it is usually used for
the submerge-arc welding of liquefied gas storage tanks, gas bottles and pipeline steel.
