MPI on AISI 410
MPI on AISI 410
(OP)
I have received NDE Report (Magnetic Particle Inspection) for wellhead material AISI 410. As per my knowledge AISI 410 is martensitic stainless steel having paramagnetic properties. Please let know wheather 410 is paramagnetic or ferromagnetic and applicability of MPI on it.

RE: MPI on AISI 410
Look at this :
" Martensitic and Precipitation Hardenable Stainless Steels
All Martensitic and most precipitation Hardenable stainless steels are ferromagnetic. Due to the stresses induced by the hardening transformation, these grades exhibit permanent magnetic properties if magnetized in the hardened condition. For a given grade, the coercive force, Hc, tends to increase with increasing hardening, rendering these alloys more difficult to demagnetize.
Examples of martensitic stainless steels are Type 410, 416, 420, 440B and 17-4. "
