A202
Description:
A202 is titanium calcium type Cr18Ni12Mo2 stainless steel electrode. As the deposited metal added Mo, it has good corrosion resistance, heat resistance and crack resistance, especially against chloride ion pitting benefits. AC-DC dual-use, with excellent performance of the process
use:
Used for welding work in organic and inorganic acid (non-oxidizing acid) medium and 06Cr17Ni12Mo2 stainless steel or as dissimilar steel welding.
