Hobart HN-590 Submerged Arc Welding Flux - 55 lb Bag - S669610-055

HN-590 - HN-590 is an agglomerated basic type flux producing weld deposits with good mechanical properties at low temperatures. HN-590 may be used in single and multiple pass applications with no limitations on weld metal thickness. HN-590 is suitable to use on both DC and AC polarities. HN-590 has good weldability, good slag removal in groove welds and good resistance to cracking and porosity. Typical applications include structural steels, high strength low-alloy (HSLA), quenched and tempered and other low alloy steels. Depending on the application, the HN-590 flux may be used with the composite electrodes such as Metalloy EM12KS, EM13KS, and other low alloy composite electrodes.

FLUX CHARACTERISTICS:

Flux Type:         HN-590
Polarity:             DC or AC
Max Current:     1200A

The properties listed above are typical of either DC electrode positive (reverse polarity), or variable balance
AC (VBAC) square-wave with 66% electrode positive / 34% electrode negative.
