Specification:
EN760 SA AR 1 88 AC H5
AWS A5.17/5.23 F7A0-EL12 F7A2-EM12K
Applications:
Butt and flat fillet welding of miniature LPG tanks, ships, vehicles, agricultural
implements, machinery, boilers, bridges, structural steels.
Characteristics:
SJ501 is an agglomerated aluminate-rutile type flux.
Metallurgical behavior: High silicon and manganese pick-up is obtained.
Grain Size: 10-60 meshes
Basicity: 0.7 (B||W)
The welding performance is excellent. Slag detachability is very good, especially at
high speed. Welding porosity scarcely occur. Its welding speed can travel up to
120cm/min. It is particularly useful for welding tube-web-tube joints of finned tubes.
SJ501 is useful for welding thin plate in single pass and limited pass. The flux has
low moisture pick-up and granular stability. As the bulk density is low, so is the
consumption rate. Damp flux should be re-dried at 300-350ºC for 2 hours. Rust,
grease and moisture on the weldment should be removed before welding.
