A002 line with GB E308L-16 
 Rather AWS E308L-16 

 Description: A002 is a titanium calcium type of ultra-low carbon stainless steel electrode Cr19Ni10. The carbon content of deposited metal ≤ 0.04%, has good resistance to intergranular corrosion, good welding performance, drug-resistant skin red, strength, good resistance to porosity. Can be AC ??and DC. 


 Uses: Used for welding low carbon stainless steel Cr19Ni10 can also be used for temperature below 300 ℃ 0Cr19Ni11Ti corrosion-resistant stainless steel, mainly used for synthetic fibers, fertilizer, oil and other equipment.

 Note: 
 1. 200-250 ℃ before welding electrodes shall be baked 1h. 
 2. As far as possible dc power supply, current is not too large.
