Product Description
Submerged Arc Welding Flux SJ501
Specification: EN760 SAAR 1 88AC H5
AWS A5.17/5.23 F7A0-EL12K 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.
Basicity: 0.7(BllW)
Damp fux should be re-dried at 300-350 °C for 2 hours. Rust,grease and moisture on the weldment should be removed before welding.
