AWS E90C-B3 or E62C-B3 (W53030) Weld Metal

AWS E90C-B3 is a weld metal formulated for joining alloy steels. Cited properties are appropriate for the post-weld heat treated (PWHT) condition. E90C-B3 is the AWS designation for this material. W53030 is the UNS number.

It has a moderately high tensile strength among the alloy steel welding fillers in the database.

The graph bars on the material properties cards below compare AWS E90C-B3 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.
