Product Description

Specification: EN760 SA FB1 65 AC H5


                    AWS A5.17/5.23 F6A0-EL8 F7A2-EM12K F7A4-EH14


Applications:


Horizontal welding of oil storage tanks, ships, bridges, pressure vessels, penstocks, boilers and structural

steels.



Characteristics:



TY-SJ101 is an agglomerated fluoride-basic type flux.



Metallurgical behavior: Slight silicon pick up. The behavior of manganese is neutral.



Basicity: 1.8 (B||W)



TY-SJ101 assures excellent weldability, and the welding bead appearance is beautiful and the slag is easy


to remove.



The diffusible hydrogen content in deposited metal is less than 5ml/100g, so it has very good toughness



at low temperature, therefore, crack resistance is extremely high.



It is suitable for submerged arc twin-wire, tandom and multi-wire welding as well as for welding with the


two-run technique.



Damp flux should be re-dried at 300-350ºC for 2 hours. Rust, grease and moisture on the weldment



should be removed before welding.
 

Packing Details: Welding flux SJ101 packing: Brown paper bag with anti-moisture plastice lining. 25



kgs/Bag, 40 Bags/Pallet, 1 MT per pallet.
