Issues regarding surface inspection of stainless steel threaded joints
Thread Content
This post was last edited by New little friend on 2009-8-19 at 10:59. Our company has manufactured a type of small-diameter threaded joint, with external threads on one end and internal threads on the other; it requires non-destructive surface testing, and its material is 0Cr18Ni9. I believe that only water-based fluorescent penetrant inspection can yield good test results, but the drawback is its lower sensitivity. I wonder if fellow sailors and experts have any better methods. I hope to get some advice from someone more experienced. Thank you! Your opinions are also welcome.
