SJ501:GB/T 12470-90 F5A0-H08A
AWS A5.17 F7AZ-EL8
Equivalent to Lincoln 760 welding flux
1.Description:
LH-SJ501 is a bonded type acid flux composed mainly of aluminium and oxides with ball form granule about 10-60 mesh in size.Its basicty is 0.5-0.8.It can be used on AC or DC power source.It provides good welding usability,easy slag removal,excellent anti-porosity property and beautiful bead appearance.
2.Applications:
In combination with H08A or H08MnA wire,this flux is suitable for welding of gascylinders,membrane water-cooled wall of boilers,ect.
3.CHARACTERISTICS:
1.LH-SJ501 is an agglomerated aluminate- rutile type flux.
2. Metallurgical behavior: High silicon and manganese pick- up is obtained.
3.Grain size: 10 to 60 mesh.Basicity: 0.7( BIIW).
4. The welding performance is excellent.
Slag detachability is very good, especially at high speed.
Welding porosity scarcely occur.
5. Its welding speed can travel up to 120 cm/ min. It is particularly useful for welding tube- web- tube joints of finned tubes.
6.LH-SJ501 is useful for welding thin plate in single pass and limited pass.
7.The flux has low moisture pick-up and granular stability . As the bulk density is low so is the consumption rate.
4.Caution:
1.Damp flux should be re-dried at 300-350 Centigrade for 2 hours.
2.Rust, grease and moisture on the weldment should be removed before welding.
