Fracture Analysis on Cracking of 16Mn Flange

Abstract:

16Mn flanges cracked during producing.Physical and chemical analysis of the cracking 16Mn flange were performed,it was found that the chemical composite of 16Mn flange agreed well with standard NB/T 47008-2011,but the physical properties of it were abnormal,the sharpy values of which were far below standard requriemet.furthermore,the metallographic of the cracking 16Mn flange were bulky network polygonal ferrite and pearlite.And this was the main reason that caused the failure.And on the end some control motheds were suggested to this accident.
