AWS E16-8-2 (W36810) Weld Metal

AWS E16-8-2 is a weld metal formulated for joining stainless steels. Cited properties are appropriate for the as-welded condition. E16-8-2 is the AWS designation for this material. W36810 is the UNS number. Additionally, the ISO numeric designation is ES16-8-2.

It has a fairly high ductility among stainless steel welding fillers. In addition, it has a moderately high electrical conductivity and a fairly low base cost.

The graph bars on the material properties cards below compare AWS E16-8-2 to: stainless steel welding fillers (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
