Product Description

Submerged arc welding flux LH-SJ301 for Spiral steel pipe

Specification:
GB/T5293 F4A0-H08A F5A0-H08MnA
Equivalent to: 
AWS-A5.17 F6A0-EL12 F7A0-EM12K
DIN BSC 198AC10SKM


Description: 
1. SJ301is a kind of silicon-calcium-type sintered flux. 
2. Grain size: 10-40(2.0-0.45mm) meshes. 
3. Basicity of 1.0-1.1. 
4. Either alternating or direct current can be used(welding wires must be connected with the positive electrode when direct current is used). 
5. Performance: Fine detachability and fine appearance of weld. 

Usage: 
1. The welding flux is For the submerge-arc welding of low-carbon, low-alloy steels, and thin steel sheets(fast single-way and double-surface welding). 
2. For liquefied gas storage tanks, gas bottles and pipeline steels. 
 
Cautions: 
1. The oil soil, moisture, iron and other foreign substances must be removed from the welding joint. 
2. It is better to use direct current. 
3. The welding flux must be baked under 300-350ºC for 2 hours.
