Dye Penetrant (PT) Testing for Industrial Valves
Like magnetic particle testing, PT testing can be used to detect surface discontinuities. PT testing is also the only choice for surface examination of non-magnetic materials. These include:
- 300 Series Stainless Steels: The 300 Series stainless steels are austenitic alloys made primarily of chromium and nickel.
- Monel: Monel is a nickel superalloy with excellent corrosion resistance.
PT is a very accurate method of exposing pits and cracks and determining if they are deep or just on the surface.
