Mob:+8618563406379 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. It should be re-dried under 300-350ºC for 2 hours. Rust,grease and moisture on the weldment should be removed before welding.3.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.
