Not good. . For operating conditions of over 400 degrees, weld materials with a higher carbon content are generally chosen. . The carbon content of 316L is less than 0.03%. . The standard requirement is to use ER316H with a carbon content of 0.04–0.08%. .
The welding wire was used incorrectly; in this case, does it need to be cut off and rewelded?
A lower carbon content may result in lower high-temperature strength. The safety factor is there, so it’s not a big problem. . If it can be cut off, then cut it off. Be more cautious. .
