AWS E410 (W41010) Weld Metal

AWS E410 is a weld metal formulated for joining stainless steels. Cited properties are appropriate for the post-weld heat treated (PWHT) condition. E410 is the AWS designation for this material. W41010 is the UNS number. Additionally, the ISO numeric designation is ES410.

It has the lowest base cost among stainless steel welding fillers. In addition, it has a moderately high electrical conductivity and the highest thermal conductivity.

The graph bars on the material properties cards below compare AWS E410 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.
