ER80S-B3L

AWS A5.28 ER80S-B3L

80S-B3L is a low alloy filler designed to produce high strengths on 2 1/4 & Cr-1 Mo steels found in high temperature/high pressure piping and vessels. This alloy is identical to the ER90S-B3 except it has a lower carbon content maximum that will lower the strength and exhibit greater resistance to cracking and used more often when welds are left in the as-welded condition. It may also be used on carbon steels to Cr-Mo base metals. Controlled preheat, interpass and postheat treatment may be needed to avoid cracking.
