AK-E309Mo-16
Standard:
EN ISO 3581-A:E (23 12 2 L) R 1 2
AWS A5.4 E309Mo-16
Description: AK-E309Mo-16 is a Cr23Ni13Mo2 stainless steel electrode with rutile coating. AC and DC dual-use, can
perform all-position welding. The electrode has good welding process performance. Because the weld metal
containsmolybden-um, it has better corrosion resistance, crack resistance and oxidation resistance than A302.
Application: It is suitable for welding the same type of stainless steel vessels that are resistant to sulfuric acid medium
(sulfur ammonia) corrosion, and can also be used for welding stainless steel linings, clad steel plates, and dissimilar
steels.
