AWS E219 (W32310) Weld Metal

AWS E219 is a weld metal formulated for joining stainless steels. Cited properties are appropriate for the as-welded condition. E219 is the AWS designation for this material. W32310 is the UNS number. Additionally, the ISO numeric designation is ES219.

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

The graph bars on the material properties cards below compare AWS E219 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.
