A106B steel pipes can be accepted with some concessions
Thread Content
The Cr% level in A106B steel pipes is above the specified limit, and the total amount of the 5 major elements is also above the limit. However, since it has already been manufactured as a finished component, can it be accepted with some concessions?

The decision to accept the material with concessions can only be made by the owner; it’s unlikely. Exceeding the specified chemical composition levels indicates that the material does not meet the standards, so it should be replaced.
No, the property owner will definitely have you replace it
Re-test again. . Chemical analysis method. .
In the pressure vessel industry, there can be no room for carelessness; those that do not meet the standard requirements should be avoided as much as possible. If problems or accidents occur, the consequences are too severe to bear, so caution is essential.
Can you take a screenshot of the chemical element contents and send it? There are too many lines in the copied text, making it difficult to read.
It’s recommended to have it rechecked; 106B isn’t a rare material these days, so it shouldn’t cause any problems under normal use.
