E347L-16
E347L is Cr19Ni10Nb stainless steel electrode with ultra-low carbon and Nb stabilizer of titanium calcium type coating, which has excellent resistance to intergranular corrosion. AC-DC dual-use, can be all-position welding.
use:
Commonly used in 06Cr18Ni11Ti stainless steel welding and petrochemical equipment corrosion surfacing.
