AK-E318-16
Standard:
EN ISO 3581-A:E （19 12 3）Nb R 1 2
AWS A5.4 E318-16
Description: AK-E318- 16 is a rutile-type coating containing niobium-stabilized Cr19Ni12Mo2Nb stainless steel electrode.
AC and DC dual-use, can perform all- position welding. The welding process performance is excellent, and the deposited
metal has better resistance to intergranular corrosion than A202 and A207.
Application: It is suitable for welding urea synthesis towers, vinylon equipment and other parts that are in contact with
strong corrosive media, such as 06Cr17Ni12Mo2Ti, 06Cr17Ni12MoNb and other stainless steel structures.
