DELTA FERRITE IN SA 335 P92 STEEL

Dear Sirs,

I am working with a piping fabrication company. We many times carry out welding on P92 pipes.

Presently, we have a customer who wants to measure %age of delta ferrite in P92 pipes & welds. We are in touch with several people but none have named any specific equipment which could measure delta ferrite content in P92 pipes & welds.

We also do not know what should be the maximum acceptable content of delta ferrite present in P92.

It's a problem for us. Please help !!!
