The Mo content in F316L is above the limit; is it acceptable?
Thread Content
I would like to order a batch of special-grade material F316L with a Mo content of 3.05%, which is 0.05% above the specified limit. Is it usable? If used, what are the performance-related risks?
No problem, the instrument still has errors
Even for elemental deviations, there are standards to be followed. Chemical elements are the most fundamental technical requirements in steel materials. Once it exceeds the standard, if judged based on the deviation criteria, it remains unqualified and is considered a defective product; as for whether it can be used, that depends on the specific operating conditions.
Was this generated by a spectrometer or through composition analysis? . There is an error.
On the material list, it’s probably PMI
It shouldn’t be PMI on the material list, right? There are non-metallic elements, right? Check the relevant material standards; the standards specify the allowable errors
