Product Description
AWS-A5.17 F6A0-EL8 F7A2-EM12K EN760 SA CS 1 89 AC H5 
Equivalent to Lincoln 760 welding flux 

Butt and fillet welding of 
 LPG tanks, Structural steels, Gas bottles, Pipeline steel, 
Especially Spiral pipes welding. 


1. LH-SJ301 is an agglomerated calcium-silicate type welding flux 
2. Metallurgical behavior: High silicon pick-up is obtained. When the manganese content in wire is less than 1.5%, also a manganese pick-up. 
3. Grain size: 10 to 60 mesh Basicity: 1.0(BIIW) 
4. Regularly shaped welds are deposited without reducion of area or interface notches. 
5. Slag detachability is good. A short slag is produced, thus allowing circumferential welding on small-diameter workpieces without the risk of uncontrolled slag. 
6. The production of large pipes(especially spiral pipe welding) is a typical application fo this flux 
7. Relatively high manganese pick-up is obtained, thus allowing the flux to be used with wires with a low Mn content.
