Sometimes these elements will "creep" away from thinner sections, such as a strut, or where a thin section (such as a strut) cools too quickly to allow a sufficient amount of carbon and graphite to form in the matrix. This will cause that section to "ring". If that's what's doing it, you can find out by holding the strut firmly in your hand to see if the ringing lessens. I'm not saying this is what's going on in the piano you're having this trouble in. It could be something else. But this is often the cause of plate ring.
