A002
A002 is an low carbon 18%Cr-8%Ni stainless steel welding electrode with rutile coating. AC/DC both can be applied. The deposited metal contains ≤0.04% carbon, with good weld intercryctalline corrosion resistance, good welding performance, red resistance, good strength and good porosity resistance.
The product is applicable for welding ultra-low carbon Cr19Ni10 and 06Cr18Ni11Ti stainless steel structures, mainly used for manufacturing synthetic fibers, fertilizers, petroleum and other equipment.

1. Before welding, the welding electrode should be baked at 300℃ for 1h.
2. Operating with DC power supply as much as possible, and the current should not be too large.
