文摘Some cracks have been detected in the oCr18Ni9Ti stainless inlet and outlet pipe bends of a boiler by non-desturctive detection. Analysis of chemical’compositions and metallographic structure and the fractographic analysis with the electron microscope of the cracked pipe bands are presented. The causes for cracking of the pipe bands are studied.
