双相钢S22053可以做磁粉检测吗？它的磁性如何，各位同仁有没有人做过？

磁粉检测适用于铁磁性材料的原材料、零部件和焊接接头表面、近表面缺陷的检测，该材料可以通过永久磁铁识别，或者通过保留剩余磁场能力来识别。关于常用铁磁材料的判定，也可参照附录A(参考ASTM E1444)列举的材料类别。This procedure is suitable for use on ferromagnetic materials for surface or near surface defects of raw materials, components and welded joints which may typically be identified by testing with a permanent magnet or by the ability to retain a residual magnetic field. For the determination of commonly used ferromagnetic materials, the material categories listed in Appendix A (refer to ASTM E1444) can also be referenced.
注：磁粉检测不适用于奥氏体不锈钢和其它非铁磁性材料的检测。双相不锈钢和超级双相不锈钢可能会显示出磁性，但不能认为它们是铁磁性材料，这些材料应用液体渗透法进行检测。Note：Magnetic particle testing is not suitable for the detection of austenitic stainless steel and other non-ferromagnetic materials. Duplex and Super Duplex Stainless Steels may exhibit ferromagnetic properties but shall not be considered ferromagnetic. Liquid penetrant shall be used for examination of these materials.

应该还是应用渗透检测好一些

LPT优于MT，对于双相钢

一般都用渗透检测，磁粉检测效果不好

用渗透检测好一些

毕竟是不锈钢，还是渗透较磁粉靠谱些

汇质源质量

一般都是选择渗透。

不用MT，PT最好
