Welding Flux Sj301 for Sub Arc Welding Wire Aws-A5.23/Aws-A5.17

Welding flux:TY. SJ301Certification: ABS, CCSSpecification:AWS A5.17 F6A0-EL8 F7A2-EM12KEN760 SA CS 189 AC H5
Applications:Butt and fillet welding of minature LPG tanks, Structural steels, Gas bottles,Pipeline steel, especially Spiral pipes welding.
Characteristics:1. SJ301 is an agglomerated calcium-silicate type welding flux2. metallurgical behavior: High silicon pick-up is obtained. When themanganese content in wire is less than 1.5%, also amanganese pick-up.3. Grain size: 10 to 60 mesh Basicity: 1.0(BIIW)4. Regularly shaped welds are deposited without reducion of area or interfacenotches.5. Slag detachability is good. Ashort slag is produced, thus allowingcircumferential welding on small-diameter workpieces without the risk ofuncontrolled slag.6. The production of large pipes(especially spiral pipe welding) is atypicalapplication fo this flux7. Relatively high manganese pick-up is obtained, thus allowing the flux to beused with wires with alow Mn content.
Necessary process before welding:Damp flux should be re-dried at 300-350 ºC for 2hours. Rust, grease andmoisture on the weldment should be removed before welding.
Usage:The flux is fit for the submerged arc welding of low carbon steel and low alloysteel, as well as the fast single-way and double-surface welding of thin steelsheet. And it is usually used for the sumberged arc welding of liquefied gasstorage tanks, gas bottles, and pipeline steel.
Package:25kg per kraft paper bag; 1000kg per Jumbo bag
Cautions:1. The welding flux must be baked for 2hours at the temperature of 300-350ºC before build up welding2.Some foreign substances such as rust ,grease and moisture on theweldment should be removed before welding.Chemical composition of the flux SJ301(%):SiO2+TiO2CaF2Al2O3+MnOCaO+MgOSP30-405-1325-305-10≤0.05≤0.05Mechanical properties of the deposited metal:Wires matchedStandard modelsYield
