A222
Description:
A222 is a titanium-calcium type Cr19Ni13Mo2Cu stainless steel electrode, because the deposited metal contains Cu, in acidic medium has better corrosion resistance than other stainless steel electrode. Has excellent welding performance, AC and DC can be used.
use:
For welding the same type of stainless steel equipment containing Cu.
