Reason Analysis on Cracks in Long Axle of 16Mn Steel
The defects were found by ultrasonic inspection in a long axle of 16Mn steel. Chemical composition analysis, low magnification observation, metallographic examination and fracture analysis were used to characterizing defects and analyze the reason. The results showed that the crack defects originated from nonmetallic inclusions in raw materials and extended under processing pressure.
