SB-511

[azizur447]

The specification of chemical composition of SB-511 UNS N08330 (Ni-Fe-Cr-Si Alloy) does not specify of Fe composition just mention Fe remainder. I got a MTR of the above material chemical composition comply but not include the Fe content. But they certify the material is SB-511 UNS N08330. Should I accept the MTR.

 

[metengr]

Is iron (Fe) listed as balance? If so, accept.

According to SB-511

Footnote B in Table 2

(B) Element shall be determined arithmetically by difference. This refers to Fe.

 

[azizur447]

No it does not say balance

 

[metengr]

If it states remainder, the MTR is still acceptable. The iron content can be determined arithmetically by difference.

 

[EdStainless]

For elements that are listed as rem, bal or ellipsis (...) there is no specification limits.
