| Abstract: | The mechanical properties and surface quality of 15MnNbR steel produced by normal rolling, normalizing and testing, always meet the technical requirement, but many steel plates are disqualification by non-destructive test. Causes are investigated by optical microscopy and electron probe. Improving methods are put forword. |
