AWS E80C-B3L or E55C-B3L (W53130) Weld Metal

AWS E80C-B3L is a weld metal formulated for joining alloy steels. Cited properties are appropriate for the post-weld heat treated (PWHT) condition. E80C-B3L is the AWS designation for this material. W53130 is the UNS number.

The graph bars on the material properties cards below compare AWS E80C-B3L to: alloy 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.
