AWS E2553 (W39553) Weld Metal

AWS E2553 is a weld metal formulated for joining stainless steels. Cited properties are appropriate for the as-welded condition. E2553 is the AWS designation for this material. W39553 is the UNS number. Additionally, the ISO numeric designation is ES2553.

It has a fairly high tensile strength and a moderately low ductility among stainless steel welding fillers.

The graph bars on the material properties cards below compare AWS E2553 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.
