Description
Recently, austenitic stainless steels are generally used for the material of atomic reactor's heat exchangers. But stress corrosion cracking of stainless steel heat exchangers under condition of high temperature water has been reported. So we have made some experiments to study the stress corrosion cracking of stainless steel heat exchangers in high temperature water.<br>The results obtained are as follows:<br>(1) Cold drawing of stainless steel tubes and existence of chloride ion and dissolved oxygen in water accelerate the occurrence of stress corrosion cracking.<br>(2) Seal welding by TIG method between the tube plates and the tubes accelerates the crack initiation.<br>(3) Solution treatment of cold drawn stainless steel tubes decreases the sensibility to stress cracking.<br>(4) The eddy current method is effective for nondestructive inspection of stress corrosion cracking in expanded parts of stainless steel heat exchangers.
