A242

According with GB E317-16
Corresponding with AWS  E317-16


Introduction: A242 is a kind of low-carbon Cr19Ni13Mo3 stainless steel electrode with lime-titania type coating. The Mo content in the deposited metal is higher than that of A202. It has better corrosion-resistance to non-oxidizing acid (such as sulphuric acid, sulphurous acid and phosphoric acid) and organic acid. It is also pitting corrosion-resistant. AC/DC.


Uses: Used for welding the same types of stainless steel materials, composite steel and dissimilar steel.
