Cause of cracks in welded joints of higher-pressure deaerator made of 16MnR steel
In this paper,the cause of cracks in the welded joints of higher-pressure deaertor made of 16MnR steel for thermal power plant was studied with electron mieroscopy,X-ray spectroscopic analysis,da/dN and △Kth test.The results show that the ckaeks were the delay cracking which propagated in a way of stress corrosion craeking in operation.
