Firebox Steel
Firebox Steel
(OP)
Hello,
I am curious about what the term Firebox means in steel. For example, I am evaluating an existing pressure vessel with SA-285-Gr.C Firebox for the structural steel. The equipment was made in 1971.
Thanks,
Eddy

I believe that the first spec with that name was A30.
These tended to be better grade steels for their time with tighter chemistry and property ranges.
However most of them were not fine grain steels, they were Si killed.
This term (FBQ) has also appeared in A201 and A212, though not all of these steels are the same.
If you don't have original MTRs I would suggest finding a location where you could take some destructive test samples. Knowing chemistry and tensile will answer a lot of your questions.
