Specification: EN760 SA CS 1 89 AC H5
Conform with: AWS A5.17 F6A0-EL8 F7A2-EM12K
Applications:
Butt an flat fillet welding of miniature LPG tanks, ships, vehicles, agricultural implements, machinery,
boilers, bridges, structural steels.
Characteristics:
SJ301 is an agglomerated calcium-silicate type welding flux.
Metallurgical behavior: High silicon pick-up is obtained. When the manganese pick-up.
Grain Size: 10-60 mesh
Basicity: 1.0 (B||W)
Regularly shaped welds are deposited without reduction of area or interface notches. Slag detachability is
good. A short slag is produced, thus allowing circumferential welding on small-diameter work pieces without
the risk of uncontrolled slag. The production of large pipes (especially spiral pipe welding) is a typical
application for this flux. Relatively high manganese pick-up is obtained, thus allowing the flux to be used
with wires with a low Mn content.
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.
