Product Description

Agglomerated Submerged Arc Welding Flux Sj301 for Steel Structure 

SJ301 TECHNICAL DATA

1)Specifications: 
AWS-A5.17 F6A0-EL8 F7A2-EM12K EN760 SA CS 1 89 AC H5
2)Description:
SJ301 is an agglomerated calcium-silicate type welding flux. Basicity: 1.0 (B//W) It is gray and round grain, mesh: 10-40. 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 workpieces 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. 
3)Caution:
It should be re-dried under 300-350ºC for 2 hours. Rust, grease and moisture on the weldment should be removed before welding. 
4) Applications: 
The flux is fit for the submerge-arc welding of low-carbon steel and low-alloy steel. Butt and flat fillet welding of miniature LPG tanks pipeline steel, , ships, vehicles, agricultural implements, machinery, boilers, bridges, structural steels.
