    Indication Analysis on Magnetic Particle Testing for Metering Valve of 9Cr18 Stainless Steel

    • The linear indication was detected on the surface of metering valve of 9Cr18 stainless steel in magnetic particle testing process, and the reason of linear indication was analyzed by microstructure examination. The results showed that the indication was caused by chromium segregation.
