Product Description

Specification: EN760 SA CS 1 89 AC H5


                 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:


TY-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.
