Intercrystalline Stress Corrosion Cracking of Heat Exchanger Tubes of Austenitic Chromium--Nickel--Molybdenum Steel No. 1.4571 (X10CrNiMoTi18 10)

The cause of stress-corrosion cracking of austenitic X10CrNiMoTi18 10 heat exchanger tubes supposedly resistant to intercrystalline corrosion was investigated. A brown layer of magnetite, Fe sub 3 O sub 4 , was found on the tubes. It was concluded that the failure was probably caused by the precipit...

Description
Summary:The cause of stress-corrosion cracking of austenitic X10CrNiMoTi18 10 heat exchanger tubes supposedly resistant to intercrystalline corrosion was investigated. A brown layer of magnetite, Fe sub 3 O sub 4 , was found on the tubes. It was concluded that the failure was probably caused by the precipitation of Ti sub 2 S at the grain boundaries, but no experimental evidence for this could be given. 4 ref.--AA
