Hi Friend,

Can anyone explain me that why does MPI test use for LF2 mateiral and not going to use LP test?

LF2 is a ferromagnetic material, therefore, MPI can be performed. The advantage to MPI is that surface and near surface defects may be located depending on method and technique used. As a rule, if the material is strongly magnetic, use MPI. If non-magnetic use LPI.

A-350, section 11.3 permits PT as well. As per jwhit, MT is preferred because subsurface discontinuities can be located.
