Equivalently: AWS-A5.17 F6A0-EL12 F7A0-EM12K F7A0-EL8 DIN BSC 198AC10SKMDescribe:
LH-SJ301 Versatile flux for welding of ordinary structural steel and boiler steel matching with suitable SAW wire (such as EM12, EM12K and EL8), which can obtain smooth weld bead with flat weld interfaces free from undercut. Stable arc and good slag detachability, form shot slag in welding, no phenomenon of slag-flow are other special features of TH-SJ301. It can be used to the Multi-pass weld and multi-wire weld, especially to weld pipelines in various diameters.
Flux type: Silicon Calcium
Basicity index: 1.0
Grain size: 2.0mm-0.28mm (10-60meshes)
Usage :
When applied to various welding wires, such as AWS EL12 (LINCOLN L60), AWS EM12K (LINCOLN L-61), it can weld Low-carbon steels, Low-alloy steels and pressure vessels.
It is fit for fast welding of thin steel sheet like gas steel tanks and membrane water- cooled wall in boiler factory.

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.
