Ferriscope?
Ferriscope?
(OP)
Dear all,
Has anybody used a ferriscope to measure the ferrite percent in duplex and super duplex stainless steels?
What are the pitfalls with its use?
Any recommended manufacturers?
Thanks,
Herc

The Fisher units are reliable, but not field robust. You have to handle them carefully.
I have found them very reliable.
Surface condition of the welds can have some impact. Very uneven welds may give incorrect results.

However, no instrument can do anything about macro-inhomogeneity of any sample.
