Introduction:

A202 is a, calcium-titanium coated, Cr18Ni12Mo2 stainless steel electrode. Mo in the deposited metal offers good corrosion-resistance, heat-resistance and crack-resistance. It is especially tough fighting the corrosion caused by fluorine. The electrode can work on AC/DC.

 

Uses:

It is used in welding the 06Cr17Ni12Mo2 stainless steel that is applied in the media of organic acid and inorganic acid.
